concept 1
using a table of values
how to use a table of values: step 1: create the table
step 2: choose a set of x values
step 3: substitute each x value (left side column) into the equation
step 4: evaluate the equation (middle column) to arrive at the y value
using two points
how to use two points on a graph: Step 1: Find the y-intercept and plot the point.
Step 2: From the y-intercept, use the slope to find the second point and plot it.
Step 3: Draw a line to connect the two points.

using y=mx+b
how to use y=mx+b: step 1: in the equation y = mx + b for a straight line, the number m is called the slope of the line
step 2: let x = 0, then y = m • 0 + b, so y = b. The number b is the coordinate on the y-axis where the graph crosses the y-axis
concept 2
From the equation of a line, ⇒ y=mx+b ⇒ m here is the slope.
