Answer:

Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = -
x + 3 ← is in slope- intercept form
with slope m = - 
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= 
Answer:
109
Step-by-step explanation:
I used a app, I also assumed that the “2x2” of the equation meant 2x^2
I agree the answer is 225 and you can also use the calculator too.
