Answer:
y-4=-3/4(x+5)
Step-by-step explanation:
y-y1=m(x-x1)
y-4=-3/4(x-(-5))
y-4=-3/4(x+5)
Let x: the number of restaurants gift cards, and y: numbers of movie theaters gift card
50x+20y=450
x+y=15, so x=15-y
50(15-y)+20y=450
750-50y+20y=450
y=10
x=5.
As a result, Mr. Thompson buys 10 movie theaters give cards, and 5 restaurants gift cards. Hope it help!
