Answer:
y=-2x+24
Step-by-step explanation:
The slope is -2 because the slope of a perpendicular line is the opposite fraction(flip numerator and denominator) and the opposite sign (negative/positive).
Use y=mx+b to find out the y intercept.
10=-2(7)+b
10=-14+b
24=b
Your equation would be
y=-2x+24
hooe this helps :)
