Slope-intercept form is y = mx + b
m is the slope
b is the y-intercept
In y = x,
slope = 1
y-intercept = 0
To graph:
- put a point on 0 on the y-axis {0 is the y-intercept}
- from there, use the slope of 1 to get the next point. Move up 1 and to the right 1 and put another point {slope is rise/run}
