Answer:
y = 7x - 14
Step-by-step explanation:
If the given line has slope -1/7, then any perpendicular line has the slope which is the negative reciprocal of -1/7. That is +7.
Apply the slope-intercept formula for the equation of a straight line, using 0 for y, 2 for x and searching for the y-intercept value b:
0 = 7(2) + b. Then b = -14, and the desired equation is y = 7x - 14.

Answer:
A digit 2
Step-by-step explanation:
628/8 = 78
thus making 628 divisible by 8
Answer:
y=3
Step-by-step explanation:
A = 1/2 * b * h
A = 178.5
b = h + 4
178.5 = 1/2 * (h + 4) * h
357 = h^2 + 4h
h^2 + 4h - 357 = 0
(h - 17)(h + 21) = 0
h - 17 = 0
h = 17
h + 21 = 0
h = -21 .....not this one because it is negative
b = h + 4
b = 17 + 4
b = 21
so the height is 17 inches and the base is 21 inches <==
