Where does the line y=-4x + 9 cross the y-axis? O aty = -4
O at x = 9
O at y = 9
O at x = -4

at y = 9

Step-by-step explanation:

where m = slope and b = y-intercept.

The question asks where does the line cross y-axis. That means what is the value of b or what is the y-intercept.

Because it is y-axis, we don't need x-axis/value or term. The value of b is 9, intercept y-axis at (0,9).

Therefore, the answer is third choice.

3

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3
