mohamed elsayed branch concept 3: How to use y=mx+b?
4.you write the equation by only knowing the slope and the y intercept point.
1.m= the slope. you use m to find the rise and run and to find if the line is negative or positive.
2.b= y intercept this is where the line cuts the y axis point that has a x as a zero is the intersection this shows that you will find a point on the line 0,B
3.for example you use the slope m and 0.B to graph a line. the use of the formula y = mx + b to determine the y-intercept, b the replace x and y in the formula and replace with the coordinates of one and then replace m with calculated value number

Mustafa elmouselhi: how to graph a line
The first part in concept one is a table of values, this is an ordered pair of numbers in which are there to substitute variables, for example, an equation of a line and other functions. to find the value of a variable or find the value of an missing number.
Using y=mx+b
you first start by placing the y intercept which is the B value then the y intercept is the place where the line would cross the y axis From the y-intercept point, use the slope to find a second point. To map the second point, the slope's numerator indicates how many units to push up or down from the intercept, and the slope's denominator indicates how many units to switch left or correct. Attach the two points and draw arrows at both ends to indicate that the line extends forever.
The third part of concept one is called using one point and a slope. This basically is starting off with a number at graph for example lets say thats 7, so you start with 7 rise and zero run. and the number you add is 3/4, so you add 3 to the rise and 4 to the run.
the two pints on a line are the x1 and y1 and x2 and y2 which are an equation to help find the slope the line goes through two points which are x1 and y1 and x2 and y2

Hamza shoukry: how to find slope of a line
This is the first part of the second concept. This starts of with you counting how much is the rise on the graph and how much is the run on the graph so lets say i got a 3/4, then i write it and if i can simplify it you simplify it. This is one way for solving these equations.
y=mx+b the M is is the slope which is multiplied on the x and the B is the y-intercept and that is the point where the line crosses vertically on the y axis this equation is named the slope-intercept form

!
In the second part graph all of your points and connect all of them.
In the first part find in the graph,the m is equal to rise over run.
For the fourth part use the m
and the b to create the equation which
is y=m+b.
n the second part look for the y intercept which is
the part where the y intercept goes through y axis i
This is the second part of concept 2 and this is using slope formula, This video will better explain it.
