The word of means to multiply. So you multiply 72 by 5/9 and get 40
Answer:
slope = 2 and y- intercept = - 2
Step-by-step explanation:
Calculate the slope m using the slope formula
m =
with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (2, 2)
m = = = 2
The y- intercept is the value of the y- coordinate at the point where the line crosses the y- axis, that is
y- intercept = - 2
C because I rounded up to 5 which would be 75 and it was a little less so C
Answer:
(5, - 6 )
Step-by-step explanation:
Given the 2 equations
- 8x - 10y = 20 → (1)
- 8x - 6y = - 4 → (2)
Multiply (2) by - 1
8x + 6y = 4 → (3)
Add (1) and (3) term by term to eliminate the x- term, that is
- 4y = 24 ( divide both sides by - 4 )
y = - 6
Substitute y = - 6 into either of the 2 equations and solve for x
Substituting into (1)
- 8x - 10(- 6) = 20
- 8x + 60 = 20 ( subtract 60 from both sides )
- 8x = - 40 ( divide both sides by - 8 )
x = 5
solution is (5, - 6 )
