Write the equation in point-slope form of the line that passes through the given point and has the given slope.
(4, -7); m = -1/4

• y +7 = -1/4(x - 4)
• y - 4 = -1/4(x + 7)
• y+ 7 = 4(x - 4)
• y - 7 = -1/4(x - 4)

What is the standard form of a linear equation?

• y = mx + b

• Ax + By = C

• y - y₁ = m(x - x₁)

Which of these represents the point-slope form of a linear equation?

• y - y₁ = m(x - x₁)
• Ax + By = C
• y = mx + b

Rewrite the equation into Standard form

• 5x + 8y = 56

• -5x + 8y = 56

• 8x + 5y = 56

• 5x + y = 7

Write the equation of the line through the points (−6, −19) and (2, 5).

• y = −7/2x + 12

• y = 3x + 11

• y = −7/2x − 40

• y = 3x − 1

Write the equation of the line with slope -2 through the point (7, −1).

• y = −2x + 15

• y = −2x − 15

• y = −2x + 13

• y = −2x − 13

Write the standard form of the equation of the line that passes through (-2, -3) and (2, -5).

• 2x + y = -7

• x + 2y = -8

• 2x - y = -1

• x - 2y = -8

Which of these represents slope-intercept form of a linear equation?

• y - y₁ = m(x-x₁)
• Ax + By = C
• y = mx + b
