Question

A. 1/3 x +y=72x + 6y = 12Questions What’s the slope Y intercept?Number of solutions?

Answer 1

$\begin{gathered} \frac{1}{3}x+y=7 \\ \\ 2x+6y=12 \end{gathered}$

To identify the slope (m) and y-intercept (b) you write each equation in slope intercept form by solving for y:

$y=mx+b$

First equation:

Substract 1/3 x in both sides of the equation:

$\begin{gathered} \frac{1}{3}x-\frac{1}{3}x+y=-\frac{1}{3}x+7 \\ \\ \\ y=-\frac{1}{3}x+7 \end{gathered}$

Slope: -1/3

Y-intercept: 7

Second equation:

Substract 2x in both sides o
