Question

Directions: Use each graph below to write the equation of the line in slope-intercept form y=mx + b. Make sure to show your work.

Answer 1

Explanation:

Y=mx+b

Slope (m) is rise over run.

1. rise= 4 run=5 therefore, slope=4/5

y=4/5x+b

b= y intercept

b= 4

Y=4/5x+4

2. rise= 1 run= 2 slope = -1/2

b= -1

Y= -1/2x - 1
