Two line segments that will never intersect
Answer:
y = 0.25x - 9.5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 0.25 , then
y = 0.25x + c ← is the partial equation
To find c substitute (6, - 8) into the partial equation
- 8 = 1.5 + c ⇒ c = - 8 - 1.5 = - 9.5
y = 0.25x - 9.5 ← equation of line
The student will have $135 in her bank account at the end of the ninth week. You can fine this out by finding out the amount she deposits a week and to do this you would take the $30 and divide it by 2 because she had $30 at the end of the second week.
30/2=15
So you see that the student deposits $15 each week, so to find out how much money she will have in 9 weeks you will multiply her $15 by 9.
15x9=135
So the student will have $135 at the end of the ninth week.
