Opal walked from school to home, which was a distance of 12 miles. She walked
at a rate of 4 miles per hour. The graph
represents the remaining distance Opal
had to walk.

a. Find the slope of the line.

Slope = -4

x intercept = 3

Step-by-step explanation:

See attachment for graph

Required

a. Determine the slope

b. Find the x intercept and explain what it represents

a. The slope

To calculate the slope, we start by selecting any two corresponding values of x and y from the graph.

Next, we calculate the slope (m)

b. The x intercept

This is the point where

From the graph.

 when

This implies that:

After 3 hours, the distance left to cover is 0miles.

In other words, she arrived home in 3 hours

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
