How do you graph #y = 2x - 3#?
The equation is in
M - the M stands for the slope of the line
For example if the M was replaced with 3/2 then you would go up 3 and then go over 2 in the positive direction
If the slope is a negative like -4, then you would go down 4 and over 1 in the positive direction
b - the b stands for the y-intercept
For example, if the b was replaced with a 7, you would start at the origin, and move up 7.
If the y-intercept was negative like -5 then you would start at the origin, and move down to 5.
