Question

What is the x-coordinate of the x-intercept of the line that passes through points (-5, 3) and (1, -3)?

Answer 1

One way to solve this is to find the equation of the line in slope - intercept form:
y = mx + b
Then y can be set to zero to find the required coordinate. Do you want any help to do this?

Answer 2

Please. :p

Answer 3

Lets go! The slope m is found from the formula:
\[m=\frac{y _{2}-y _{1}}{x _{2}-x _{2}}=\frac{-3-3}{1-(-5)}=\ ?\]

Answer 4

so its -6/6?

Answer 5

Yes....or simplified would be?

Answer 6

1?

Answer 7

-1 right? -6/6 is -1 :) so that is your 'm' (slope)

Answer 8

:) thankss
