Answer: D.8
Step-by-step explanation:
y-intercept means the point of the line crosses the y-axis, where x = 0.
y = mx + b represent most linear equation, where m is the slope and b is the y-intercept.
Step 1: Find the slope of the line, choose two points: (-2,16) and (1,4).
slope =
=
=
= -12/3 = -4
Step 2: Solve b by choose one point to plug in. (1,4)
y = mx + b
4 = -4(1) + b [Plug in the value of x, y, and slope]
4 = -4 + b [Add 4 on both sides]
8 = b
Therefore, the y-intercept is D.8
