1) jonas got a $35 gift card, each app cost $1.75
x = number of apps
y = money remaining
-> immediately cross out D, you can't buy 31.5 apps
$1.75 per app
-> 2 apps = $3.50 (35 - 3.50 = $31.50 left)
-> 4 apps = $7 (35 - 7 = $28 left)
-> 6 apps = $10.50 (35 - 10.50 = $24.50 left)
look for the answer choice that matches this = A

2) the y-intercept (the point on the y-axis) is -5.
to find the slope, look at the dotted points.
slope from a graph = rise/run
you go from (0, -5) to (0, -2)
-> the rise is 3 (going up the y-axis), and the run is 5 (going left and right in the x-axis)
y = 3/5x - 5 (F)

3) ashley earns $6 per hour and $1.50 for each pair of shoes
e = total earnings
h = number of hours
e = 6h + 1.50(10) <- 10 is for the 10 pairs of shoes
e = 6h + 15.00 (C)
--------------------------------------------------------------------------------------------
4) $2.65 per mile, $1.50 initial charge
y = total cost
x = number of miles
y = 2.65x + 1.50 (J)
--------------------------------------------------------------------------------------------
5) y-intercept = 4
-> we find the slope (rise / run)
rise = 4
run = 3
equation: y = 4/3x + 4 (C)
✧ hope this helped!
