Answer:

Step-by-step explanation:
Let:

We need to eliminate one of the variables, so let's use elimination method. First multiply (1) by 2

Now subtract (2) from 2*(1) in order to eliminate x:

Solving for y:
Multiplying both sides by -1

Finally, replacing the value of y in (1)

Solving for x:
add 41 to both sides:

Multiply both sides by 1/2:

Hey there!
B in a slope intercept form equation is the the y intercept. It dictates where the line will cross the y axis, and therefore the line's placement altogether. This is because if there was no y intercept, the line would only be shaped by the slope, and would start at 0.
Hope this helped!
Answer:
Sometimes this fraction can be further simplified by dividing the numerator and the denominator by their greatest common factor. ... Divide the numerator by this number. If the result is zero, the simplified slope of the line is also zero.

Percent means per one-hundred...
(40/100)*(80/100)=3200/10000=32/100=32%
