Match

Match each equation with the correct form.

$Ax+By=C$

$y=mx+b$

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

standard form

slope-intercept form

point-slope form

Multiple Choice

Which two pieces of information do you need to write an equation in point-slope form?

A point (x1, y1) and the slope (m).

Two points (x1, y1) and the y-intercept (b).

The slope (m) and the x-intercept (x).

A point (x1, y1) and the y-intercept (b).

Match

The general form of point-slope form is:

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

Match each variable with its description.

$m$

$x_1$

$y_1$

slope

x-coordinate of a point

y-coordinate of a point

Match

A line has a slope of 2 and passes through the point (-1,5).

Match each value with the variable it represents in point-slope form:

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

-1

$m$

$x_1$

$y_1$

Drag and Drop

A line has a slope of 2 and passes through the point (-1,5).

Drag & drop the correct values into point-slope form:

y -

( x -

)

Drag these tiles and drop them in the correct blank above

Multiple Choice

Which is the equation of a line that passes through the point (4, 7) and has a slope of -4.

$y-4=-4\left(x-7\right)$

$y-7=-4\left(x-4\right)$

$y+7=-4\left(x+4\right)$
