Writing the equation of a straight line

Write the equation in slope-intercept form: 5x - 2y = 12

• y = 5/2x - 6
• y = -5/2x - 6
• y = 5x +12
• y = -5x + 12

Determine the slope and y-intercept from the following equation: y = 4/3x - 9

Match the correct equation to the graph

• y = 4x

• y = 9x

• y = 10x

• y = 3x

Find the slope and y-intercept of the following:

3x - y = 9

• Slope = 3, y-intercept = -9
• Slope = 9, y-intercept = 3
• Slope = 3, y-intercept = 9
• Slope = -1, y-intercept = 3

What is the equation of the line?

• y= x

• y= x+0

• y=2x-1

• y= 3x

What is the equation of a line that has a slope of -8 and a y-intercept of 2?

• y = 8x + 2

• y = 2x + 8

• y = -8x + 2

• y = 2x - 8

State the equation of the straight line -8x+2y=4 in the form of y=mx+c.

• y= 1/2 + 8x -4
