Question

Help please!What is the x-intercept of the line?X=-21 Y=-64X=-15 Y=-48X=-9 Y=-32

Answer 1

Given data:

The first coordinate is (-21, -64).

The second coordinat is (-15, -48).

The expression for the equation of the line passing through the given points is,

`\begin{gathered} (y-(-64))=(-48-(-64))/(-15-(-21))(x-(-21))_{} \\ y+64=(16)/(6)(x+21) \\ 3y+192=8x+168 \\ 8x-3y-24=0 \end{gathered}`

Substitute 0 for y to get x intercept.

`\begin{gathered} 8x-3(0)-24=0 \\ 8x=24 \\ x=3 \end{gathered}`

Thus, the x-intercept is (3,0).
