Write the following equation in slope-intercept form:
4x - 3y = 12

• y = -4/3x + 3
• y = -4x + 12
• y = 4/3x - 4
• y = 4/3x - 12

What is the slope:

5x + 10y  = 30

• m = -1/2

• m = 1/2

• m = 3

• m = 1/3

Which equation is written in STANDARD form?

• y = 1/2x + 2
• y - 3 = -5(x + 2)
• -7x + 2y = 9
• 3x + 2 = y

Identify the formula used to find slope.

• $m=\frac{y_2-y_1}{x_2-x_1}$

• $m=\frac{y_1-y_2}{x_1-x_2}$

What is the slope-intercept form of a line?

• Ax + By = C

• y = mx + b

• y - y1 = m(x - x1)

• y = Ax + By

Write the slope intercept form of the equation x - 3y = 6

• y = -x - 2

• y = x + 2

• y = 1/3x - 2

• y = -1/3x + 2

Write the standard form of the equation for the line:

y = 1/4 x + 4

• x + 4y = 8

• x - 4y = -16

• y = x + 16

• 4y + x = 8

What is this formula?

 $y-y_1=m\left(x-x_1\right)$  

• point slope

• standard form

• slope

• slope-intercept

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)
