Find the slope of a line given these

points on the line:( -4,8) (3, -2)

Give the slope and y-intercept of the

line that has passes through these points

(3,0) (6,2).

Give a 2nd point that would fall on the line

that passes through (5,4) and has a slope of ½.

Write the equation of this line:

Identify which if any pairs of equations are parallel or perpendicular:

A) y = 3x + 4 E) y = 3x + 2 B) y = 4x – 3 F) y = 4x C) y= -1/3x G) y= 1/3x +8 D) y= -0.25x +6

Write 2 equations that are parallel to one

another & Write 2 equations that

are perpendicular to one another.
