Make sure you can find slope from

two points using the slope formula.

Write the slope formula in the box:

7. Can you find the slope of the line that passes through each pair of points. Your answer will be a

positive or negative integer, a positive or negative fraction, undefined, or zero.

a. 3, ) and (6, )( 7 1

b. 5, ) and (5, )( 8 2 c. − , ) and (− ,− )( 3 3 7 5

6. Can you find the slope of a vertical or horizontal line?

a) b)

m = _________________ m = _________________

5. Can you find the slope and y intercept of a graphed line?

m = __________

b = __________

Can you write this function as an equation in Slope-Intercept Form?

____________________________________

4. Can you look at function in Slope-Intercept Form and say what the slope and y intercept are?

a) xy = 3 − 2 b) − xy = 5 + 7 c) xy = 32

m = ______ m = ______ m = ______

b = ______ b = ______ b = ______

3. Can you look at a function in standard form, change it to slope intercept form (y=) and say what the

slope and y intercept are?

a) x4 + y = 7 b) –10x + 5y = 30

Slope:_____________ Slope:_____________

y-intercept:_________ y-intercept:_________

2. Given a linear equation, can you write several new equations that are parallel to the original?

Given: x 6y = 21 + 1 Give some functions of parallel lines:

_________________________ _________________________ _________________________

parallel line 1 parallel line 2 parallel line 3

Remember...

Parallel lines have equal ___________________, but the ______ __________________ is different.

1. Can you graph equations using slope and y-intercept?

a) y = 4x – 6 b) x y = 3 c) 2x + 3y = 1

0) YOU CAN DO IT!!!!
