Write the equation of the line in slope-intercept form with slope m = 4 through the point (-2, 5).

• y = 4x - 13

• y = 4x + 13

• y = 4x - 3

• y = 4x + 3

Write the equation of the line in standard form through the points (-6, -19) and (2, 5).

• -3x - y = -1

• -3x + y = 1

• 3x - y = 1

• y = 3x - 1

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

• y = (-2/3)x + 4

• y = (2/3)x + 4

• y = (3/2)x + 4

• y = (-3/2)x + 4

Put this into standard form:

y = 3x + 2

• y + 3x = 2

• 3x + y = 2

• 3x - y = - 2

• 3x - 2y = 2

Write an equation in slope-intercept form that goes through the points (-3, -4) and (3, 4)

• y = 3/4x + 4

• y = 3/4x

• y = 4/3x

• y = 4/3x + 4

Find the equation that represents the line going through (0, 2) and (-4, 0).

• y = 1/2 x - 4

• y = 1/2 x + 2

• y = 2x + 2

• y = -2x - 4

Write an equation of the line containing (-1,1) and (4,-9)

• y = -2x

• y = -2x - 1

• y = 1/2 x

• y = (-1/2)x -1

Write the equation of a line that passes through the point (1,4) and has a slope of 9.

• y= 9x-4

• y= 9x-5

• y= 9x+4

• y= 9x+5
