2-85.

Without graphing, identify the slope and y-intercept of each equation below. Homework Help ✎

1. $y = 3x + 5$

• In the form y = mx + b
m = slope
b = y-intercept

1. $y=\frac{5}{-4}x$

• If the b is not present in y = mx + b,
it is understood that b = 0.

1. $y=3$

• Similar pattern as in part (b).

• Slope = 0

1. $y=7+4x$
