Find the slope given the two points



Slope Practice Name__________________________

Alg 1 Date_____________B_______

Find the slope given the two points using the formula. Simplify if needed. FORMULA:

1. ( 3, 5) (-2, 0) 2. (–4, –2) (2, -10) 3. (3,7) (3,-5) 4. (5,-2), (4,-2)

# 5-8: Match the line to the type of slope.

____5.

____7.

Plot the points & draw a line through them. Without calculating, tell type of slope - positive, negative, zero, or undefined. Then find “m” by counting rise over run – show count on graph!

9. (1, –4) and (5, –8)

Type of slope: ____________ m= Type of slope: ____________ m=

10. (3, 6) and (–3, 6)

Type of slope: ____________ m= Type of slope: ____________ m=

Try these: Find the value of x or y so that the line passing through the two points has the given slope. You can graph or use the formula.

12. (–3, y), (–9, –2); m =1 13. (–1, 4), (x, 3); m =

14. (8, 1), (1, y); m = –1 15. (9, y), (3, 2); m=
