Fill in the Blanks

Find the slope of the line that passes through the points (9,4) and (0,1)

Fill in the Blanks

Find the slope of the line that passes through the points (-2,5) and (-2,10)

Point-Slope Form

Multiple Choice

Write the equation in point-slope form for the line that contains the points

(-2, -3), (4, 3)

• y - 3 = 1(x - 2)

• y + 3 = 1(x + 2)

• y -3 = -1(x + 2)

• y + 3 = -1(x - 2)

Multiple Choice

For the equation

y - 3 = 2(x + 4),

the line has a slope of 2 and contains what point?

• (-4, 3)

• (3, -4)

• (-3, -4)

• (-4, -3)

Multiple Choice

Write the equation in point-slope form of the line that passes through the given point and has the given slope.

(4, -7); m = -1/4

• y + 7 = -1/4(x - 4)

• y - 4 = -1/4(x + 7)

• y + 7 = 4(x - 4)

• y - 7 = -1/4(x - 4)

Slope-Intercept Form

Fill in the Blanks

Write an equation of a line in slope-intercept form that passes through the points (1,-2) and (-2,13).

Type your answer with NO spaces

Multiple Choice

Write the equation of the line.

• y= -1x-3

• y= -3x-1

• y=-1/3x-1

• y= -3x-3

Fill in the Blanks

 $3x\ -\ 2y\ =\ 18$  

Rewrite the equation above so that it is in slope-intercept form. 

Type your answer with NO spaces

Standard Form

Fill in the Blanks

Write an equation in standard form that passes through the point (2,7) and has a slope of -4

Type your answer with NO spaces

Fill in the Blanks

 $\frac{1}{2}x-2y=\frac{5}{2}$  

Rewrite the equation above so that it is in standard form.

Type your answer with NO spaces.
