How to graph a line?
Yassin Ali
Table of values:
This method is commonly used it is very simple and straightforward you first need to find the ordered pairs after that plot and graph. An example would be having a graph and having y=x+10 under that there would be a X and Y column and numbers in the x column and empty in the Y column and you'll have to figure out the Y column so you can plot it on the graph.
Two points:
Using this method you would need a graph from the start. To begin you will have to plot the points, after that you would have to connect them to make a line. The same example goes for the two points, you would be having a graph and having y=x+10 under that there would be a X and Y column and numbers in the x column and empty in the Y column and you'll have to figure out the Y column so you can plot it on the graph.
1 point and a slope:
Plot the point then use the slope formula to find the rise then the run. All this process has to be completed on the starting point, count the rise then the run to find the answer don’t get mixed up and do it the other way around and don’t forget to connect the points with a line. A example would be is you being given a slope number and a number y intercept number and you have to find the line on the graph given
y=mx+b:
This method follows a strict order of steps which begins when plotting the y intercept which would be the B value. The y intercept is the place that is being crossed by the y axis. An example would be having the equation Y=2x+4 and trying to plot it on the graph so you can find your answer.

The slope formula is another method you can use to find the slope of a line. It is y2 - y1 over x2 - x1. For example, if your two points were 1,3 and 2,4, you would do 4-3 over 2-1 = 1 over 1. So, the slope is 1.
Rise over Run
Rise over run is one of the three ways you can find the slope of a line. The rise over run method counts how many horizontal and vertical steps 2 points are away from each other. To do this method, you will need to points on a graph. Next, you will draw a RIGHT triangle that connects the two points together. Then, count how many vertical jumps there are on the right triangle and THEN, count the horizontal jumps. After counting the jumps, create a fraction where the numerator is the rise and the denominator is the run. Make sure to simplify your fraction if possible. The fraction is the slope of the line.

Equation of a line
The equation of a line is y=mx+b. The m in this equation is the slope. The b is the y-intercept. You can use this equation to find the slope of a line.

How to use y=mx+b - Abdulwassa
m = slope
The slope of a line is a number that measures its "steepness", usually denoted by the letter m. It is the change in y for a unit change in x along the line. Notice that for every increase of one unit to the right along the horizontal x-axis, the line moves down a half unit. It therefore has a slope of -0.5.
b = y-intercept
An intercept is a point on the y-axis, through which the slope of the line passes. It is y-coordinate of a point where a straight line or a curve intersects the y-axis. The point where the line crosses the x-axis is the x-intercept and the point where the line crosses the y-axis is the y-intercept.

How to write the equation of a line?

The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept.
How do you find the equation of a line example?
The equation, y = mx + b, is in slope-intercept form for the equation of a line. When an equation is in this form, the slope of the line is given by m and the y-intercept is located at b. For example, a line with the equation y = 2x + 4 has a slope of 2 and a y-intercept of 4.
