What is the formula to find the slope from two points?

• (y2 - y1) / (x2 - x1)

• 2y - 2x / 2

• y1 - y2 / x1 - x2

• x2 - x1 / y2 - y1

Write an equation in point-slope form for a line passing through the point (3, 4) with a slope of 2.

• y - 4 = 2(x - 3)

• y = 2x - 3

• y - 4 = 2x + 3

• y - 4 = 2x

Convert the equation y - 5 = 2(x + 1) from point-slope form to slope-intercept form.

• y = 2x + 5

• y = 2x - 1

• y = 2x - 7

• y = 2x + 7

Graph the linear equation 2x - 3y = 6 in standard form.

• y = (3/2)x - 6

• y = (2/3)x + 6

• y = (3/2)x + 6

• y = (2/3)x - 2

Solve for the y-intercept in the equation y = 3x + 2.

If the slope of a line is 4 and it passes through the point (2, 5), what is the equation of the line in point-slope form?

• y = 5x - 2

• y - 5 = 4(x - 2)

• y - 5 = 4x

• y = 4x + 2

Convert the equation 4y - 2x = 8 from standard form to slope-intercept form.

• y = (1/2)x + 2

• y = 2x + 8

• y = 8x - 4

• y = 4x - 2

Graph the linear equation y = -2x + 4 in standard form.

• y = 2x + 4

• y = 4x - 2

• The correct answer is: y = -2x + 4

• y = -4x + 2
