Answer:
240
Step-by-step explanation:
Using the straight line formula; y=mx+c, take two points, for example, (4, 80) and (5, 100)
m=change in y/change in x, so;
m=(100-80)/(5-4)= 20
Take point (4, 80)
80=20×4 + c
80-80=c=0
so y=20x
y=20×12=240
Answer:
You need to record interest earned :)
Step-by-step explanation:
Hope it helps :)
Add -2y and subtract 10
2y = 4x - 10
Divide by 2
Y = 2x - 5
m= 2, b= -5
