Writing Equations of Lines:

A. Writing linear equations given the slope and y-intercept

- Find the slope (m) and y-intercept (b) [If the given information is a graph, then you will have to count by

hand to find these values.]

- Fill in m and b so you have an equation of the line in y = mx + b form. Convert to standard form if

necessary.

y = ________ x + ____________

↑

(

Put m here!)

(

Put b here!)

16.) Find the equation of the

17.) Find the equation of the

18.) Write the equation of a line

line with slope of 5 and y-

given line in slope-intercept

that has the same slope as

intercept of -2. Write in

form.

− and has a y-intercept

standard form.

of 1. Write in standard form.

B. Writing linear equations given the slope and a point

• plug slope = m into y = mx + b

• name your point (x, y) and plug these values in for x and y

• solve for b

• plug m and b back into y = mx + b **(leave x and y as variables!**

• convert to standard form, if necessary

19.) Find the equation of the line with slope of -2

20.) Find the equation of the line with slope of

and going through (-1, 3) in slope-intercept form.

and going through (6, -2) in standard form.
