Answer:
Step-by-step explanation:
I'm going to assume you mean passes through the point (-2,5) since -2 and 5 could mean a lot of different things
To find the perpendicular line's gradient, you would know that m1*m2 = -1
In this case m1 = 7, so m2 must be -1/7
Now we substitute the gradient into the equation
y = -1/7x + b
To find b, we substitute (-2,5) into the equation above
5 = -1/7*-2+b
5 = 2/7 + b
b = 33/7
Therefore the equation of the line is
y = -1/7x+33/7
Answer: 16
Step-by-step explanation: I don’t know
-5 and 3
you do thos so you can eliminate x and solve for y then substitute the answer to y in one of the equations to solve the equation
The answer: ( x ; y ) = ( -2 ; 6 )
Ok done. Thank to me :>
