Linear Equations Review

What is the slope-intercept form of a linear equation?

• y = mx + b

• y = mx - b

• y = ax + b

• y = mx^2 + b

What is the standard form of a linear equation?

• Ax - By = C

• Ax + By = D

• Ax + By = C

• Ax + By = D + E

What does the y-intercept represent in a linear equation?

• The y-intercept represents the slope of the line.

• The y-intercept represents the point where the line intersects the x-axis.

• The y-intercept represents the maximum value of the function.

• The y-intercept represents the point where the line intersects the y-axis.

Convert the equation y = 2x + 3 to the standard form.

• 2x - y = -3

• 2x + y = 3

• x - 2y = 3

• y = 2x - 3

Convert the equation 3x - 2y = 6 to the slope-intercept form.

• y = (3/2)x - 3

• y = (3/2)x + 6

• y = (3/2)x + 3

• y = (3/2)x - 6

What is the y-intercept of the equation y = -5x + 2?

• -5

• 0

• 1

• 2

What is the slope of the equation 4x + 2y = 8?

• -2

• 0

• 4

• 2

Write the equation in slope-intercept form for a line with a slope of -3 and a y-intercept of 4.

• y = 3x + 4

• y = -3x - 4

• y = -3x + 4

• y = -4x + 3

Write the equation in standard form for a line with a slope of 1/2 and a y-intercept of -3.

• 2y - x = -6

• 2y + x = -6

• y - 2x = -6

• y + 2x = -6

What is the y-intercept of the equation 2x - 3y = 9?

• -3

• 0

• 2
