Answer:
A. y=x+7
Explanation:
All of the answers are in y-intercept form (y=mx+b where m is the slope and b is the y-intercept), so the two points are used to solve for slope and y-intercept. Immediately, (0,7) gives the y-intercept because this point intercepts the y-axis at 7. Slope is found by dividing the rise over run between the two points. The points rise in y from 2 to 7 for a total of 5 units and the points run from -5 to 0 for a total of 5 units. Rise divided by run would be 5/5, simplified to a slope of 1. From this, slope=m=1 and y-intercept=b=7. Plugging these values into y=mx+b, the final answer is y=x+7.

Answer:
read explanation
Step-by-step explanation:
rearrange equations to form y=mx+b
-2x+4=2y
-x+2=y
-y=-2x-5
y=2x+5
use these equations to find slope and y intercepts, and match those with the right graph
slope of first: -1
slope of second: 2
y-int of first: 2
y-int of second:5
Answer:
DF= 33
Step-by-step explanation:
The ratio is equal to 6:5:1 Which can be changed into 18:15:3
Since DE=18 and EF=15 you simply add and = 33
I believe the answer is 23.52 because if u add 19.60 to 20% thats what u get
