1. Estimate the slope of the line from its graph.

1

2

3

-2

2. Use the point and slope to find one additional point on the line through (-2, 1) with slope(m) =1.

(2,5)

(2, -3)

(-1,-1)

(3, -3)

3. Find the slope and y-intercept of the line 2x + 10y = 40

m= 3, intercept=(1/5)

m=(1/5), intercept 9

m =(-1/5), intercept 5

m=(-1/5), intercept 4

4. Find the equation of the line that has a slope of 3 and passes through (1, 2)

y = 2x - 1

y = 3x - 1

y = x – 3

y = 3x- 2

5. Write an equation of the line through the point (2, 5) and perpendicular to y = 2x + 7

y=½x+4

y = 2x + 6

y=–½x+6

y = x + 5
