Graph Given Slope and an Ordered Pair

Find the slope and y-intercept of the graph of the equation: y = –2x + 7

• m= - 2 b= - 7

• m= 2 b= - 7

• m= - 2 b= 7

• m = 1/2 b= - 7

What equation represents point-slope form?

• y = mx + b

• y - y₁ = m ( x - x₁ )

• y = mx - b

• 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 – 4 = – (x + 2)
