Answer:
(X, Y) = (2, 1)
Step-by-step explanation:
Equation put together is
-2x - 3 (5x - 9) = -7
Just take away 1 from the digit above and add 10 to regroup.
the answer is the first one when you you graph it on a graph you can see it's perpendicular
Answer: y = -x - 6
Step-by-step explanation:
The equation of a line in slope-intercept form is given as :
y = mx + b , where m is the slope and b is the y - intercept.
From the question :
m = - 1
b = -6
substituting into the formula , we have
y = -1(x) - 6
y = -x - 6
