The easiest way to do this is to put the equation in
y = mx + b form. To do this, isolate the
y on one side of the equation. The number or fraction in front of the variable x (identified by the letter m in the original equation) is your slope.
![17x-12y=-36 \\ (17x-12y)-17x=(-36)-17x \\ -12y=-17x-36 \\ (-12y)/-12=(-17x-36)/-12 \\ y= \frac{17}{12}x+3](https://tex.z-dn.net/?f=17x-12y%3D-36%20%5C%5C%20%2817x-12y%29-17x%3D%28-36%29-17x%20%5C%5C%20-12y%3D-17x-36%20%5C%5C%20%28-12y%29%2F-12%3D%28-17x-36%29%2F-12%20%5C%5C%20y%3D%20%5Cfrac%7B17%7D%7B12%7Dx%2B3)
The slope of the equation is
17/12 AKA (
m=17/12).
Hope this helps!
I=PRT
Interest=Principal times Rate times Time
Principal=amount invested in itially
Rate=rate in decimal form
time=time in years
so
given
principal=2000
rate is 3.5%=0.035
time=4yrs
so
I=(2000)(0.035)(4)
I=(8000)(0.035)
I=280
A. the interest earned was $280
B. add interest to the principal
280+2000=2280
the ballance was $280 after 4 yrs
You subtract 13 from both sides of the = sign so ×=12
