Algebra Chapter 3 Review

If m = 3 and b = 6, what is the correct slope intercept equation?

How would you write the equation with a slope of 2/3 and a y-intercept of -3

Find the slope of the line that passes through

(1, -19) and (-2, -7)

HINT: Use the slope formula

• -4

• 4

Find the slope of the line that passes through (-9, -6) and (-9, -10)

HINT: Use the slope formula

• 0
• Undefined
• -3
• -9

What is the equation of this line?

(Click on graph for larger picture)

• y = 2x +2
• y = 2x -2
• y = -x + 2
• Cannot be Determined

Write the equation of the line.

• $y=-\frac{2}{3}x+4$

• $y=\frac{2}{3}x+4$

• $y=\frac{3}{2}x+4$

• $y=-\frac{3}{2}x+4$

What is the Slope of the line?

• 2

• $\frac{1}{2}$

• -2

• $-\frac{1}{2}$

Give the slope and y-intercept

6x - 3y = -9

HINT: Convert to slope-intercept form (get the "y" by itself)

• slope is 6

  y-intercept is 9

• m = 2

  b = 3

• slope is 2

  y-intercept is -3

• m = 3

  b = 2

Find the slope given the points (2, −7) and (−1, 6).

HINT: Use the slope formula

• 0

What is the equation of the line that passes through the points

( 3, - 1 ) and ( 2, - 4 )?

HINT: Find the slope, plug into point-slope form, convert to slope-intercept form

• y = 3x - 4

• y = - 3x + 8

• y = 3x - 1

• y = 3x - 10
