Slopes and Equations of Lines

Find the slope of the line.

• 4/2

• -4/2

• 2/1

• -2/1

Slope is know as rise/

• run

• fall

• none

• rise

If m=3 and b=6, what is the correct slope intercept equation?

• y=3-6

• y=3x-6

• y=3x+6

• y=6x+3

Write the 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 + 1 = -3(x + 2)

• y - 1 = 3(x - 1)

• y + 2 = -3(x + 1)

Slopes of parallel lines are...

• opposite reciprocals.

• opposites.

• the same.

• always 7.
