Your answer is F.
It says she walks at a rate of 4 miles PER hour. If there is a word “per” that means you are multiplying which gives you 4p.
Lastly, it says she has a goal of walking AT LEAST 18 miles. That means 4p must be same or greater than 18.
69% is the same as .69, which is the same as 69/100
So as you can see, -3 is the y-intercept. You would make a point on (-3,0) first. Then from the point, you would go up 1 and go right 2 because the slope is a positive 1/2 slope.
