My goal for the day is:

Multiple Choice

Find the slope

• -5/3
• -3/5
• 5/3
• 3/5

Multiple Choice

Find the slope of the line that passes through:
(6,7) and (4,2)

• 2/5
• -5/2
• 5/2
• -1/2

Multiple Choice

What type of slope?

• negative
• steep
• undefined
• zero slope

Multiple Choice

Find the slope given the points (2, −7) and (−1, 6). 

• -13/3
• 13/3
• 0
• 2/3

y-intercept

also known as "b"

is the point(s) where the graph crosses the y-axis​

Slope

also known as "m"

is the ratio of rise/run​

​rise:

change in y

(vertical change)​

​run:

change in x

(horizontal change)​

​Next we will determine:

the slope & y-intercept

without graphing

7. $$3x-5y=10$$  

​Do 8.-13. on your own and check with a classmate

Indicate you have completed them for a final check​

Slope - Intercept Form:

y = mx + b

• equation is set equal to y

• slope is m (coefficient of x)

• y - intercept (0, b) is constant written after x ​
