Equation of a Line Given m and b

Write an equation in slope-intercept form of the line:

• y = 2x - 2

• y = 2x + 1

• y - 1 = 2 (x - 3)

• y - 1 = 2 (x - 2)

What equation represents slope-intercept form?

• y = mx - b

• y = mx + b

• y - y₁ = m ( x - x₁ )

• y + y₁ = m ( x + x₁ )

Write an equation in point-slope form of the line that passes through the given point and has the given slope: (–2, –1); m = –3

• y - 1 = - 3 (x - 2)

• y +2 = - 3 (x + 1)

• y + 2 = - 3 (x + 1)

• y + 1 = - 3 (x + 2)

Write an equation in point-slope form of the line that passes through the given point and has the given slope: (1, 3); m = 5

• y - 3 = 5 (x - 1)

• y - 1 = 5 ( x - 3)

• y + 3 = 5 (x + 1)

• y + 1 = 5 ( x + 3)

Identify the slope and ordered pair from the equation: y – 3 = –2 (x + 4)

• m = - 2 ( 3, - 4 )

• m = - 2 ( - 4, 3 )

• m = 2 ( - 4, 3 )

• m = 2 ( 3, - 4 )

Convert the equation to slope-intercept form: y + 4 = 4/5 ( x - 5 )

• y = 4/5x - 8

• y = 4/5x + 8

• y = 4/5x - 4

• y = 4/5x + 4
