SOLUTION: Gerry has a table of values representing a linear equation. two of them are hidden X Y -2 -6 -1 ? 0 ? 1 18

Question 177229: Gerry has a table of values representing a linear equation. two of them are hidden
X Y
-2 -6
-1 ?
0 ?
1 18

Answer by Mathtut(3670) (Show Source): You can put this solution on YOUR website!
remember if you have two points you can find the equation of the line. First find the slope which is m= change in y divided by change in x
:
X Y
-2 -6
-1 ?
0 ?
1 18
18-(-6)/1-(-2)=8........so our slope is 8...now take either of those points and use the point slope formula to get our equation
:
y+6=8(x+2)
:
y+6=8x+16
:
y=8x+10
:
now plug in our know values of x to find our y(?) points....I am out of time so I will let you do that
