Answer:
y=5x
Step-by-step explanation:
From (2,10) you rise 25 in the y direction and run 5 in the x direction to get to the next known point (7,35).
Thus, the slope is y=25/5x AKA y=5x
Answer:
Top box: Endpoint
Bottom box: Ray
Step-by-step explanation:
Assuming that the top box is supposed to be for the point shared by both rays, then it is a endpoint of the rays, as the lines do not continue past the point on the opposite side.
The bottom box will then be a ray, as no point is shown, and a arrow is used at the "end" of the line to signify that it will continue on <em>forever</em>.

Her average now is 88.
She needs to bring it up to a 90.
Let's start with if she gets a 90.
88 + 90 = 178
178/2 = 89
A 90 would only get her an average of 89, so you need to go higher.
88 + 91 = 179
179/2 = 89.5
88 + 92 = 180
180/2 = 90
She must get at least a 92 to get an average of 90.
Answer:
x=−2y+4
Step-by-step explanation:
1. flip equation
−1/
2
x+1=y−1
2. add -1 to both sides
−1
/2
x+1+−1=y−1+−1
−1
/2
x=y−2
3. divide both sides by (-1)/2
