Question

Choose the slope-intercept equation of the line that passes through the point shown and is perpendicular to the line shown.

y = one thirdx - 8
y = -3x + 12
y = 3x - 24
y = -one thirdx - 4

Answer 1

Find the equation for the first line
y = mx + b

the second, perpendicular, line will have an equation
y = (-1/m)x + c

and you will get c from the point that is on this line.
