Answer: B
explanation: on y-axis you can see the line touches -8 on graph. for the slope, rise over run could be used 9/9 =1
so y=x-8
Answer:
140 is the answer for y2 because x1 is 80 more than x2 so you would subtract y2 by 80
I think the answer is D
Hope it helps
Answer:
Step-by-step explanation:
The angles would be supplementary
45 + 5x + 35 = 180
5x + 80 = 180
5x = 100
x = 20
To find out why they are supplementary, refer to the transversal below
∠3 = ∠7 (corresponding angles)
∠8 = 180 - ∠7 (supplementary angles)
And since ∠7 = ∠3...
∠8 = 180 - ∠3 which is why (in the problem) those two angles are supplementary (adding to 180 degrees)
You can make a proportion of 8/20 to 42/x and then simply cross multiply from there to solve for y
