Question

Please help me solve question 10 on my algebra homework

Answer 1

A line equation can be written in slope-intercept form, and this form is

`y=mx+b`

Where m represents the slope and b the y-intercept. The slope given in the text is 0, therefore, we have a horizontal line. Notice that since the slope is null, the equation is reducted to y = constant.

`\begin{gathered} y=0\cdot x+b \\ y=b \end{gathered}`

Since it passes through (6, -8), our equation has a constant value for y, therefore

`y=-8`

This is our answer.
