Answer: y= 4/3x-1
Explanation:
The x of the equation is the slope and a perpendicular slope means that it is an opposite reciprocal, so we flip the numbers and the sign so the perpendicular slope is 4/3x. The b in y=mx+b is the y-intercept, the point (0,-1) is a y-intercept and the last number would be -1. So your equation would be y=4/3x-1
