Answer:

y = 7/3x -45

Step-by-step explanation:

Step-by-step explanation:

The equation is given in slope intercept form

y = –3/7x -5

The old slope is –3/7 and the new slope is 7/3. Perpendicular slopes must be opposite reciprocals of each other: m1 * m2 = –1

With the new slope, use the slope intercept form and the point to calculate the intercept: y = mx + b or -17= 7/3(12) + b, so -17=7*4+b

-17-28=b

b=-45

So y = 7/3x -45
