Add alike terms. Basically you add stuff together with the same variable! Since -8y and +3y have a y variable, they can be added together. Same with x.
-8y + 3y = -5y. This is because you’re adding 3 from a negative number.
5x - 9x = -4x. You’re subtracting 9 from a positive number.
That is as simple as it can get, so you put those two numbers in the same equation.
The simplest expression is:
-5y - 4x
The equation f a line that passes through the point (x1,y1) and has a slope of m is
y-y1=m(x-x1)
given the point (-3,7) and slope m=4
y-7=4(x-(-3))
y-7=4(x+3)
solve for y
y-7=4x+12
add 7 both sides
y=4x+19
B is answer
Answer:
the answer is b
Step-by-step explanation:
they should have the same slope so just looking at that you cancel out d. But since it says has a y-intercept of 1 then it would cancel out the other 2. d is perpendicular to it not parallel

256x-81y
