Choose the point-slope form of the equation below that represents the line that passes through the points (−6, 4) and (2, 0).

Question

pfenn1 · Answer

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

pfenn1 · Answer

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

pfenn1 · Answer

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?

anonymous · Answer

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

pfenn1 · Answer

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