Can anyone me answer these two grade 8 math questions? i have screen shots of them below.

1. y=0.5x+2
2.first one

#1
Let's find the slope. From one point to another, we are going up 1 and over 2, so the slope is 1/2 or 0.5. This function's y intercept (or where the function hits the y axis) is 2, so the equation is y = 0.5x + 2.
#2
Check it out; the speed is decreasing! As you can see, the value of the speed literally plummets as the time passes. (Car probably got stuck in traffic lol) The answer here is B.

These are my answers, but it is always helpful to double check work. Hope this helps!

200 miles.45 x 3 (charge per day times days)135$205$ - 135$ = 70$0.35x = 70divide both sides by 0.35200

Ireally don’t understand your problem do you have a better picture of it
