Answer:
The second store (10 songs for $9)
Step-by-step explanation:
15 songs/$12 = $1.25 per song
10 songs/$9 = $1.11 per song
5(11x-5)=85
55x-25=85
+25 +25
55x=110

x = 2
Answer:
y = 1/2 x + -5
Step-by-step explanation:
Slope-intercept form is y = mx + b
where m is the slope and b is the y-intercept
m is equal to change in y/ change in x ( aka horizontal change over vertical change), in the graph the horizontal change is 1 up for every 2 units right, which equals 1/2
b is the y-intercept (when x=0), if you look at the graph x=0 when y=-5
Lastly, you put in m and b into the equation to get y = 1/2 x + -5
