Find the equation of a line in the form y=Mx+b MATH HW

Find The Equation Of A Line In The Form YMxb MATH HW class=

Sagot :

Using y=mx+b form first we calculate the slope.

We'll use points (0,-8) and (-8,0).

[tex]\begin{gathered} m=(-8-0)\div(0--8) \\ m=-\frac{8}{8} \\ m=-1 \end{gathered}[/tex]

Next we calculate our b intercept

[tex]\begin{gathered} 0=-1(-8)+b \\ b=-8 \end{gathered}[/tex]

So the equation is y=-x-8
