Answer:
y=x+12
Step-by-step explanation:
y=-x+12; is a line with slope m1=-1
to find perpendicular slope of intersecting line take the negative inverse of m1. so -1*(1/(-1))=1=m2
use equation for a line of y=m*x+b and put in the point (-5,7) and solve for b=the y axis intercept
7=1*(-5)+b
7=-5+b
12=b
so
y=x+12
Answer:
D
Step-by-step explanation:
If the original price is x and you deduct 3, you'l have x - 3.
If you buy 4 of them, you multiply that price by 4, giving you 4(x - 3).
Then, if that value is equal to 27, you get 4(x - 3) = 27
Answer:
b.n(A)=1800
Step-by-step explanation:
b.n(A)=1800
x=9
Add 6 to both sides of the equation. x = 3 + 6
Add 3and 6.
x=9
the y-intercept would be -11 because slope-intercept formula is always like this; y = mx+b. b is y-intercept and m is slope. so therefore, it would be -11
