Answer:

d.

Explanation:

the slope is the factor of x.

a perpendicular slope turns the original slope upside-down and flips the sign.

the original slope is -3/7.

the perpendicular slope is then 7/3.

the only answer option with the correct slope is d.

so, d. must be correct.

let's check that (-2, 2) is on this line :

2 = 7/3 × -2 + 20/3 = -14/3 + 20/3 = 6/3 = 2

2 = 2

correct.

so yes, the point (-2, 2) is on this line, and d. is indeed correct.
