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
