Put the values as coordinates (x,y)
(1, 5) and (2, 7)
Find the slope:
(7-5)/(2-1)
m=2
Find the y intercept:
y=mx+b
y=2x+b
5=2(1)+b
b=3
<span>b.) y = 2x + 3

Hope this helps :)
Answer:
2.85 UK£
Step-by-step explanation:
To calculate the final price after the percent off, subtract the savings amount from the initial price. For example, calculate the final price of a $40 item with 15% off – remember this is a $6 savings.

Answer:
40 units
Step-by-step explanation:
Given:
Perimeter of ∆ABC = 85 units
AC = 4z
AB = 3z + 3
BC = z + 2
Required:
Numerical value of AC
SOLUTION:
Perimeter of ∆ = sum of all its sides
Perimeter of ∆ABC = AC + AB + BC
85 = 4z + (3z + 3) + (z + 2)
Use this equation to find the value of the variable, z
Collect like terms
Subtract 5 from both sides
Divide both sides by 8
AC = 4z
Plug in the value of x
AC = 4(10)
AC = 40 units
