Question

Write the equation in slope-intercept form for the line that contains (-4,-2) and is perpendicular to the line y=1/4x-7

Answer 1

m=-4
y-y1=m(x-x1)
y+2=-4(x+4)
y+2=-4x-16
y=-4x-18

Answer 2

ok so you know that it is perpendicular to 1/4x-7=y, that means that the slope of the new equation will have to be the opposite, so in this case -4x
now that you have your slope, you take your point(-4,-2) and plug it in
-4(-4)=-2
16-18=-2, therefore y=-4x-18

Answer 3

it must be the *opposite reciprocal*

Answer 4

yup
