Determine the slope and y-intercept from the following equation:   y = 3/2x + 3

• slope: 5   y-intercept:  (0,3) 

• slope: 3/2   y-intercept:  (0,3) 

• slope:  4  y-intercept:  (0,3/2)

• slope: 1/5   y-intercept:  (0,5) 

Given the following table, write the linear equation.

• y = 9x + 3

• y = 3x + 12

• y = 3x + 9

• y = 1x + 12

What is the equation in standard form of the line that passes through the point (6, -1) and is parallel to the line 8x+3y=15?

• 8x+3y=-45

• 8x+3y=10

• 8x-3y=45

• 8x-3y=10

Which equation represents a line that passes through the point (3, -4) and has a slope of 7

• y + 4 = 7(x - 3)

• y - 4 = 7(x - 3)

• y + 4 = 7(x + 3)

• y - 4 = 7(x + 3)
