# equations of lines practice

Write the equation of a line in point-Â­slope form with a slope of )(x – 3)

y – 1 = ()(x + 3)

y + 3 = ()(x – 1)

y – 3 = ()(x + 1)

Write the equation of a line in slope-Â­intercept form with a slope of -2 containing the point (1, 3).

y = -2x + 5

y = -2x – 5

y = -2x + 2

y = -2x + 7

Write the equation of a line in slope-Â­intercept form that passes through the points (-2, 1) and (4, 4).

y = 2x – 4

y = ()x + 2

y = 2x + 5

y = ()x

Write the equation of a line in standard form that passes through the points (8, 2) and (-2, -3).

+ y = -2

-x + 2y = -4

-2x + y = 1

-2x + y = -14

Write the equation of a line in slope-Â­intercept form containing the point (5, 1) that is perpendicular to the line -5x + 4y = -2.

The annual average income y of an American man with an associateâ€™s degree is given by the linear equation y = 1983x + 42,972, where x is the number of years after 1999. What does the slope of the equation represent? (Source: Based on data from U.S. Bureau of the Census, 1999Â­-2004).

The average annual income of an American man with an associateâ€™s degree in 1983.

The number of years since 1999 that the average man with an associateâ€™s degree had income.

The increase in the average annual income of an American man with an associateâ€™s degree each year.

The average annual income of an American man with an associateâ€™s degree in 1999.

The annual average income y of an American man with an associateâ€™s degree is given by the linear equation y = 1983x + 42,972, where x is the number of years after 1999. What does the y-intercept of the equation represent? (Source: Based on data from U.S. Bureau of the Census, 1999-2004).

Write the equation of a line in slope intercept form containing the point (-1, 8) that is parallel to the line 3x + y = -4.

y = 3x + 11

y = -3x + 5

y = -3x + 9

y = 3x + 9
