Answer:
y = 3x-2
Step-by-step explanation:
We can find the slope using the formula
m = (y2-y1)/(x2-x1)
= (16-4)/(6-2)
=12/4
=3
We then use the point slope form of a line
y-y1= m(x-x1)
y-4 = 3(x-2)
Distribute the 3
y-4= 3x-6
Add 4 to each side
y-4+4 = 3x-6+4
y = 3x-2
This is in slope intercept form

Answer: 560 tickets
Step-by-step explanation:
3/4 = 420/x; now cross multiply:
3x = 4(420)
3x = 1,680; now divide both sides by 3, and you get x = 560
Answer:
Carmen bought 5 pounds of coffee
Step-by-step explanation:
The cost of buying coffee is $8.44 per pound. Let us assume she bought x pound of coffee, this means that she spent $8.44x on coffee.
She went to the coffee store with $80 gift card and left with $37.80, this means that after spending $8.44x from the initial $80, she had $37.80. To find the number of pounds she bought, we are to use the following equation:
80 - 8.44x = 37.80
8.44x = 80 - 37.80
8.44x = 42.2
x = 42.2/ 8.44 = 5
x = 5 pounds.
