IF.C.07a - Graph & Compare Linear Functions

What is the equation of a line that has a y-intercept of 8 and crosses through the point(-14, 1)?

• y = 8x + 1/2

• y = -1/2x - 8

• y = -2x + 8

• y = 1/2x + 8

What is the equation of this graph?

• y = 2x + 1

• y = -2x - 1/2

• y = x + 1

• y = 4x + 1

Which graph matches the following equation? -2 + y = -3x

• A

• B

• C

• D

Determine the slope and y-intercept of the equation y - 2 = 2(x - 1).

• slope=-2, y-int(0,0)

• slope=1/2, y-int(2,2)

• slope=2, y-int=(0,0)

• slope=-1/2, y-int=(2,2)

Use the points (0,-1) and (2,0) to find the slope, y-intercept and the equation.

• slope=-2, y-int=(-1,0), EQ=y=2x-1

• slope=1/2, y-int=(1,-1), EQ=y=1/2x+1

• slope=2, y-int=(1,1), EQ=y=2x-1

• slope=1/2, y-int=(0,-1), EQ=y=1/2x-1
