Answer:

[see below]

For "slope-point" form:

Slope point (also called "Point-slope") form is: [tex]y-y_1=m(x-x_1)[/tex]

[tex](x_1,y_1)\text{ -Coordinate} \\m\text{ -Slope}[/tex]

Finding the Slope:

We need to find the slope of the line given.

Slope is: [tex]m=\frac{y2_-y1}{x_2-x_1}[/tex]

We are given the points (2,-1) and (-2,-2).

[tex]m=\frac{-2-(-1)}{-2-2}=\frac{-1}{-4}=\boxed{\frac{1}{4}}[/tex]

The slope of the line is 1/4.

Creating the Point-Slope Equation:

Replace 'm' with 1/4 and '(x1, y1)' with (2, -1).

[tex]y-y_1=m(x-x_1)\rightarrow\boxed{y+1=\frac{1}{4}(x-2)}[/tex]

[tex]\text{The equation of the graphed line in slope-point form using (2,-1) is:}\\y+1=\frac{1}{4}(x-2)[/tex]

Creating the Slope Intercept Form Equation:

Slope intercept form is: [tex]y=mx+b[/tex]

We can convert our point slope equation into slope intercept form.

[tex]y+1=1/4(x-2)\\\\y+1=1/4x-0.5 \leftarrow \text{Distribute}\\y+1-1=1/4x-0.5-1 \leftarrow \text{Subtraction Property of Equality}\\\boxed{y=\frac{1}{4}x-1.5}[/tex]

The equation of the line in slope intercept form is: [tex]y=\frac{1}{4}x-1.5[/tex] OR [tex]y=\frac{1}{4}x-\frac{3}{2}[/tex].
