Answer:
Slope is -0.6
y-intercept is -4
Step-by-step explanation:
y=mx+b
The area of a triangle is 1/2(base)(height) and since this is a right triangle the two legs can be base and height. So the area is 1/2(2x-4)^2 which becomes 1/2(4x^2-16x+16) which is simplified to 2x^2-8x+8. B is the correct answer.
I know how to but i don't know how to reply with a picture
The correct answer is x = 1/28y^2
