Which is the correct pair?
1 answer:
Answer: D
Step-by-step explanation:
Since we are given that the x value is -1, we can eliminate A and C because the -1 is in the y coordinate.
To find the proper y value, we plug x into the equation.
y=-2x+5 [plug in x=-1]
y=-2(-1)+5 [multiply -2 and -1]
y=2+5 [add 2 and 5]
y=7
Now that we have the y value, we know the coordinate (-1,7) which makes D the correct answer.
