Quick check for my answer on this question please

OpenStudy (anonymous):

passes through -2,5 and is parallel to y=2.3x+1

OpenStudy (anonymous):

My answer was y=2/3x+17 @texaschic101

OpenStudy (solomonzelman):

you mean parallel to y=2/3x+1?

OpenStudy (anonymous):

yes

OpenStudy (solomonzelman):

(you know that the slope is 2/3) So, \(\large\color{black}{ y=\frac{2}{3}x +b }\) \(\large\color{black}{ 5=\frac{2}{3}(-2) +b }\) \(\large\color{black}{ 5=-3 +b }\) \(\large\color{black}{ 8=b }\)

OpenStudy (solomonzelman):

your slope is correct, but the y-intercept was a little off. See how I solved for the b (the y-intercept)?

OpenStudy (anonymous):

its y=2.3x+8?

OpenStudy (solomonzelman):

yup

OpenStudy (solomonzelman):

but again, y=2/3x+8

OpenStudy (anonymous):

yes, I do, thanks o;
