Question

Maya is hiking up a mountain. After 4 hours she is at

800 feet elevation and after 8 hours she is at 1100 feet
elevation.
Write an equation for Maya's elevation over time.

What’s the slope?
What’s the y-intercept?
Final answer?

Answer 1

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

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
