Divide the area by the length, which should be 5
Answer:
Did you mean (-3, 7) for the first point?? If so, the answer is
D) y = -2/3x + 5
Step-by-step explanation:
Find the slope: (m)
3-7 / 3+3 = -4/6=-2/3=m
Find the y intercept (b): (plug in y, x, and m)
3=-2/3(3) +b
3=-2+b
5=b
Write equation using y=mx+b
y = -2/3x+5
To find the size of the scale, we must divide its size by 20 (because the scale is 1:20). Doing that we get 150/20=7.5m=750cm. Hope this helps!
