Answer:

Explanation:
perpendicular means negative reciprocal of the gradient
y = ¾x - 1 is perpendicular to y =

now we need to workout what the y intercept should be to make the sides equal. let's take away -1 for now


-3 = -4
To get from -4 to -3, you have to add 1. Therefore the y intercept is one. This means the final equation is:
