Equation of Lines (forms, parallel, perpendicular, scatter plots)

Write an equation in slope-intercept form for the line graph shown.

• y = 5/2 x + 2

• y = 2x + 2/5

• x = 2/5 y + 2

• y = 2/5 x + 2

Write an equation of the line that passes through the points:

(-4, -2) and (4, 0).

• y = 1/4 x - 1

• y = -1/4 x - 1

• y = 4x - 1

• y = -x + 1/4

Write an equation of the line that passes through the points:

(-3, 0) and (1, -6).

• y = -2/3 x - 9/2

• y = 3/2 x - 9/2

• y = -9/2 x - 3/2

• y = -3/2 x - 9/2

The cost for 7 dance lessons is $82.

The cost for 11 lessons is $122.

Write a linear equation to find the total cost C for L lessons. Then use the equation to find the cost of 4 lessons.

• C = 12L + 10

  4 lessons are $58

• C = 10L + 12

  4 lessons are $52

• C = 12L

  4 lessons are $48

• C = 10L

  4 lessons are $40

Write an equation in point-slope form for the line that passes through (2, 2) and has the slope of -3.

• y - 2 = 3(x - 2)

• y + 2 = -3(x + 2)

• y - 2 = -3(x - 2)

• y = -3x + 8

Write an equation in point-slope form for the line passing through (3, -3) and having a slope of 1/3.

• y + 3 = 1/3(x - 3)

• y - 3 = 1/3 (x + 3)

• y - 3 = 1/3 (x - 3)

• y = 1/3 x - 4

Write this equation in slope-intercept form:

y + 2 = 4(x + 2).

• 4x + y = -4

• y = 4x

• y = 4x + 6

• y = 4x + 10

Write the equation in slope-intercept form:

y - 1/4 = -3(x + 1/4).

• y = -3x - 1/2

• y = -3x + 1

• y = -3x - 1

• y = -3x

Write the equation in standard form:

y + 3 = -2(x - 8).

• 2x - y = 13

• y = -2x + 13

• 2x + y = 13

• 2x + y = 19
