I believe you made mistakes when calculating the y-intercept for the first equation.
The slope is correct, but the y-intercept is not.
okay
We can plug in one point given and the slope into point-slope form to find the equation. \(\sf y - y_1 = m(x - x_1)\) (-3, 7), slope = -2 \(\sf y - 7 = -2(x - (-3))\) Can you simplify that equation?
Yes. one sec
Your second equation is correct.
The table already gives you the y-intercept. (0, 5) \(\sf y = -2x + 5\)
i see
Did you simplify the equation?
i got y=13x
No.. \(\sf y - 7 = -2(x - (-3))\) \(\sf y - 7 = -2(x + 3)\) Distribute -2 into the parenthesis, can you do that?
ohhh yes, i can
that would be 5x, right?
-5
No, how did you get that?
Distributing multiplies the number on the outside of the parenthesis to every term inside the parenthesis.|dw:1452097659135:dw|
