Slope-Intercept Form Day 2

Slope-Intercept Form Day 2

1/22/2021

Today We Will...

• Review Slope

• Continue to identify & understand parts of slope-intercept form

• Write equations using clues about the slope & y-intercept

• Finish the Second Benchmark

• Start & Finish IXL Assignment

Multiple Select

Which words below can describe the slope of a line?

(May be more than more answer)

•  $\frac{rise}{run}$  

• steepness of a line

•  $\frac{change\ in\ y}{change\ in\ x}$  

• rate of change

•  $m\ =\ slope$  

Multiple Select

Which lines have a negative slope?

Multiple Select

Which lines have a slope of

 $-\frac{1}{2}\ \ \ \ or\ \ \ \ -\frac{3}{6}\ \ \ \ \ \ ?$ 

Slope-Intercept Form

Let's Break It Apart

Fill in the Blanks

What is the slope of the line

y = -5x + 6 ?

Fill in the Blanks

What is the y-intercept of the line
 $y\ =\ -\ \frac{1}{3}x\ +\ 3$  ?

Multiple Choice

Choose the correct equation to describe a line that has:

a slope of -2 and a y-intercept of 3.

• y = 2x + 3

• y = -2x - 3

• y = -2x + 3

• y = 2x + -3

Multiple Choice

Choose the correct equation to describe a line that has:

a slope of -1 and a y-intercept of 6.

• y = -x + 6

• y = x + 6

• y = -1 + 6
