Answer:
11
Step-by-step explanation:
Since both points have the same x value, we know they are vertical to each other.
One point is 4 units above the x axis, the other is 7 below the x axis.
4 + 7 = 11
Answer:
y = -3x + 4
Step-by-step explanation:
slope-intercept form: y = mx + b
Note that: m = slope
y- intercept = b
m = slope = -3
y-intercept = b = 4
Plug in the corresponding number to the corresponding variables:
y = mx + b
y = -3x + 4 is your answer.
