Answer:

Slope=75 y-intercept=500 Equation: y=75x+500

Step-by-step explanation:

We use the equation for slope to find this (1100-800)/(8-4)=300/4=150

To find y-intercept we can do the equation 800-4(75)=500

The final equation is written in slope-intercept form, which is y=mx+b with m=slope and b=y-intercept so we should have y=75x+500
