2-83.

Without graphing, identify the slope and y‑intercept of the line represented by each equation below. Homework Help ✎

1. $y=3x+5$

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

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

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

3. $y=3$

Similar pattern as in part (b).

Slope = 0

4. $y=7+4x$
