Question 332182: please solve
y= 2x+5: (8, ), (-1, ), ( ,-1)
Answer by texttutoring(324)   (Show Source):
You can put this solution on YOUR website! (8, )
You need to find the y value that corresponds to x=8:
y=2x+5
y=2(8)+5
y=16+5
y=21
The point is (8,21).
Similarly for x=-1:
y=2(-1)+5
y=-2+5
y=3
The point is (-1,3)
The last one, they give you y=-1, and you have to find x:
y=2x+5
-1 = 2x+5
-1-5 = 2x
-6 = 2x
-6/2 = x
-3 = x
The point is (-3,-1)
Hope that helps!
