\[y=mx+b\]where m=slope and b=y-intercept \[m=\frac{y _{2}-y _{1}}{x _{2}-x _{1}}\]

Once you get m, choose one of the points, substitute the values for m, x, and y into the equation, and solve for b.

y − 4 = −1/2(x + 6) y − 4 = 2(x + 6) y + 6 = −1/2(x − 4) y + 6 = 2(x − 4) can you choose one of these

Oops. I gave you the slope-intercept form of the equation, not the point-slope form. The point slope form is given by\[y – y_1 = m(x – x_1)\] You would still use the equation I gave you above for m. And then pick one of the points and substitute into the equation.

@SOUTHERNPRIDE hi and welcome to Open Study I hope we can help you understand math better, but please don't request pure answers with no explanation; that is not the aim of this site. pfenn1 has given you enough information to solve the problem, can you tell us where you are having trouble?

does it go like this? (-6,4)=(x1,y1) (2,0)= (x,y)

Close.\[(-6,4)=(x_1,y_1) ; (2,0)=(x_2,y_2) \]
