I am un able to see the photo please re try so I can help
You’re so smart, I love questions like this. Hopefully you can solve it so I can know too!
Answer:

Step-by-step explanation:
The slope-intercept form of an equation of a line:

m - slope
b - y-intercept → (0, b)
The formula of a slope:

We have two points (8, -4) and (0, 2) → b = 2.
Calculate the slope:

Therefore the equation of a line t in the slope-intercept form is:

-2 !!!!!!!!!!!!!!!!!!!!!!!
X+7.5=21.5
Subtract 7.5 from both sides
X=14 which is C
hope this helps good luck have a nice day
