The way to determine the number of solutions is to complete the problem in multiple different ways.
9(2) + 2(y) = 50. solve for y. 32=2y, y=16. It is 16 meters long.
A is the correct answer.
Point Slope Form: y - y₁ = m(x - x₁)
m = slope ⇒ -4/7
Coordinate: (-1 , 4)
x₁ y₁
All you have to do is plug in all of the information above into the formula.
y - 4 = -4/7(x +1)
I could be wrong but I think you solve for y then graph it then find where the lines intersect. You’re using ed puzzle though so just rewatch the part of the video and you’ll get the answer.
