Question

Consider the line y=-(6/5)x-2

Find the equation of the line that is parallel to this line and passes through the point (-5,-6)

Find the equation of the line that is perpendicular to this line and passes through the point (-5,-6)

Answer 1

plug in the coordinates to the slope intercept form. remember that when it's parallel, the slope stays the same and when it's perpendicular the slope becomes opposite reciprocal.

Answer 2

will the perpindicular slope be negative?

Answer 3

it shouldn't be. because you multiply the negative sign to 6/5 so that will be -6/5. and the perpendicular slope is going to be 5/6

Answer 4

when do I multiply the negative sign?

Answer 5

y=-(6/5)x-2

so you see that negative before the parenthesis? that should be understood as -6/5

Answer 6

oh ok thank you. so would the parallel equation be y=-6/5
