Answer:
f(0) = -3
x increases by 1 f(x) increase by 2
f(x) = 2x -3
Step-by-step explanation:
Looking at the graph
f(0) means when x =0 the value of y = ?
when x = 0 y = -3
f(1) means when x = 1 y = ?
When x = 1 y = -1
y increased from -3 to -1 so it increased by 2
f(x) = ax+b where a is the increase and b is the value at x =0
f(x) = 2x -3

Answer:
7
Step-by-step explanation:
Set up a proportion
12 cookies / 2 cups = 42 cookies / x Notice that cookies are on the top and cups are on the bottom of each proportion.
12/2 = 42/x Cross multiply
12x = 84 Divide by 12
x = 84/12
x = 7
He will need 7 cups to make 42 cookies.
Answer:
1/2
Step-by-step explanation:
Find two easy-to work with points
-3,2 and -1,3
slope, m = (y1-y2 ) / ( x1-x2)
(2-3) / ( -3 - -1) = -1/(-2) = 1/2
( it does not matter which point you select as x1 ,y1 or x2, y2 )
