Answer:

The equation in slope-intercept form of required line is:
\mathbf{y=(2)/(3)(x)-6}

Explanation:

We need to write equation in slope-intercept form to represent the line on the graph.

The general equation in slope-intercept form is:
y=mx+b

Where m is slope and b is y-intercept

Finding slope using formula:
Slope=(y_2-y_1)/(x_2-x_1)\\

Looking at he graph we have


x_1=3, y_1=-4, x_2=6, y_2=-2

Putting values in formula and finding slope:


Slope=(-2-(-4))/(6-3)\\\\Slope=(-2+4)/(3)\\Slope=(2)/(3)

So, we get slope m = 2/3

Using slope m=2/3 and point (3,-4) we can find y-intercept


y=mx+b\\\\-4=(2)/(3)( 3)+b\\-4=2+b\\b=-4-2\\b=-6

So, y-intercept b = -6

The equation of line having m=2/3 and b=-6 will be:


y=mx+b\\y=(2)/(3)(x)-6

The equation in slope-intercept form of required line is:
\mathbf{y=(2)/(3)(x)-6}
