Observe the graph:

\

The line passes through the points are $\"\"$ and $\"\"$ .

\

Find the slope.

\

$\"\"$ .

\

$\"\"$ (Formula for slope)

\

$\"\"$ (Substitute $\"\"$ and $\"\"$ )

\

$\"\"$ (Multiply)

\

$\"\"$ (Substitute: $\"\"$ and $\"\"$ )

\

$\"\"$ (Simplify)

\

Therefore, the slope is $\"\"$ .

\

\

The line passes through the point is $\"\"$ ; $\"\"$ .

\

Point-slope form of the equation of a line is $\"\"$ .

\

Find the point slope line equation.

\

$\"\"$ (Formula for Point-slope)

\

$\"\"$ (Substitute $\"\"$ and $\"\"$ )

\

$\"\"$ (Distributive property: $\"\"$ )

\

$\"\"$ (Subtract $\"\"$ from each side)

\

$\"\"$ (Apply additive inverse property: $\"\"$ )

\

Therefore, the slope-intercept form of the line eqaution is $\"\"$ .
