The slope is rise over run, how many times you go up (or if down it'd be a negative) and over.
The y-intercept is what point on the y axis the line passes through
Answer:
40.5
Step-by-step explanation:
This answer makes sense because we know that 50% of 90 is 45.
Since 45% of 90 is 40.5, we can self-check our answer.
Hope I helped!

The actual distance between the two towns is 15 miles.
Basically
just put the coeficinets of each variable in the apropriate row
example
ax+by=c and
dx+ey=f
would go in like this
![\left[\begin{array}{ccc}a&b&|c\\d&e&|f\end{array}\right]](https://tex.z-dn.net/?f=%20%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Da%26b%26%7Cc%5C%5Cd%26e%26%7Cf%5Cend%7Barray%7D%5Cright%5D%20)
so
3x+1=1 and
0x-1y=5
![\left[\begin{array}{ccc}3&1&|1\\0&-1&|5\end{array}\right]](https://tex.z-dn.net/?f=%20%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D3%261%26%7C1%5C%5C0%26-1%26%7C5%5Cend%7Barray%7D%5Cright%5D%20)
D is answer
Answer:
y = x - 16
Step-by-step explanation:
The <em>y-intercept</em> is the value of the function when x = 0.
If f(x) = x - 16, f(0) = 0 - 16 = -16.
A is <em>wrong</em>, because f(0) = -16(0) + 1 = 0 + 1 = 1.
B is <em>wrong</em>, because f(0) = 16(0) + 1 = 0 + 1 = 1.
D is <em>wrong</em>, because f(0) = 0 + 16 = 16.
