Kayla plans to use 60 inches of wire to build a rectangle that is seven times as long as it is wide. What will be the area of her rectangle?
98.4375 square inches.
“In our equation y = 3x – 7, what is the slope?”
3
Indicate whether or not it is a linear function.
y = –10x3
no.
Find slope
3) (0,–8), (2,–8)
0
a slope intercept form
y = mx + b
“What is the y-intercept?”
-7
Find slope and y-intercept
2x + 9y = –7x
m=-1. y-intercept 0.
find slope
2) (–1,–10), (3,6)

e graph an equation in the slope intercept form, the graph is a ---------- function
linear
3x + 4x + y = -10 rearrange in slope intercept form.
y = –7x – 10
View Graph is it function
yes.
find slope
(7,–9), (–15,3)
-6/11
View graph is it a function?
Not a function
Indicate whether or not it is a linear function. If it is, find the slope, y-intercept, and constant rate of change.
y = –9x – 22
Yes. Slope -9. y-intercept is -22. constant rate is 1.
Indicate whether or not it is a linear function. If it is, find the slope, y-intercept, and constant rate of change
2x – 5x + 3y = –2
yes. slope 1. y-intercept -2/3. constant rate 1
