What is the equation of a line that is perpendicular to the line y=- 1/4 x-1 and passes through the point (3, 7)?

a. y = -4x + 19
b. y = 4x - 5
c y = 4x+
d. y=-4x + 31

B. y = 4x - 5

Step-by-step explanation:

Line y = - 1/4 x - 1, has slope = - 1/4.

For perpendicular line slope should be negative reciprocal and = 4.

Slope point form is y - y1 = m(x - x1).

y - 7 = 4 (x - 3)

y - 7 = 4x - 12

y = 4x - 5

step-by-step explanation:

d.) yes, because the volume of the cone is greater than the volume of the sphere
