The Equation of Line

Which equation represents the following graph?

• y = 3x + 2

• y = -2x + 3

• y = 2x + 3

• y = -3x + 2

Find the equation of the line in slope-intercept form.

• y = - 1/4x - 3

• y = 1/3x + 3

• y = - 1/4x + 2

• y = 1/3x -3

Write the equation in slope-intercept form (solve for y):
2y = 10x + 14

• y = 10x + 12

• y = 10x + 7

• y = 5x + 14

• y = 5x + 7

Write the equation in solve-intercept form (solve for y):
3y = 2x + 9

• y = 2/3x + 3

• y = 2x + 3

• y = 2x + 6

• y = 3/2x + 6
