What is the solution of the system when just looking at the equations? No Graph!
Kaylis [27]

The slope-intercept form: y = mx + b

m - slope

b - y-intercept

y = 5x + 2 and y = 5x – 8

m = 5                 m = 5

b = 2                  b = -8

When comparing equations:

1. Put in <u>slope-intercept</u> form.

2. Compare the <u>slopes and the y-intercepts</u>!

This system has <u>no solution.</u>

Because we have the same slopes and different y-intercepts.

If the slopes are the same and the y-intercepts are the same, then that system has infinitely many solutions.

If the slopes are different, then that system has one solution.
