Dropdown

Write the equation of the line that goes through the points (0,2) and (4,-4).

Important formulas:

Slope formula:

m=\frac{y_2-y_1}{x_2-x_1}

Point slope formula:

y-y_1=m\left(x-x_1\right)

, where m=slope and

\left(x_1,y_1\right)

is the given point.

Using (0,2), the equation is y

x

Using (4,-4), the equation is y

)

Drag and Drop

Write the equation of the line that goes through the points (-2,-4) and (-3,-3). Important formulas:

Slope formula:

m=\frac{y 2-y1}{x2-x1}

Point slope formula:

y-y1=m\left(x-x1\right)

, where m=slope and

\left(x1,y1\right)

is the given point.

The slope is m=

Using (-2,-4), y

= m(x

)

Using (-3,-3), y

= m(x
