Answer:
slope=4/5
y-intercept = -3
Step-by-step explanation:
first we need to rewrite the expression to
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
were b is the y-intercept and m the slope
![4x-5y=15\\\\4x-5y+5y=15+5y\\\\4x+0=15+5y\\\\4x=5(3)+5(y)\\\\4x=5(3+y)\\\\\frac{1}{5}*4x= \frac{1}{5}*5(3+y) \\\\\frac{4x}{5}=3+y\\\\\frac{4x}{5} -3=3+y-3\\\\\frac{4x}{5} -3=y+0\\\\y=\frac{4x}{5} -3\\\\y=\frac{4}{5}x-3](https://tex.z-dn.net/?f=4x-5y%3D15%5C%5C%5C%5C4x-5y%2B5y%3D15%2B5y%5C%5C%5C%5C4x%2B0%3D15%2B5y%5C%5C%5C%5C4x%3D5%283%29%2B5%28y%29%5C%5C%5C%5C4x%3D5%283%2By%29%5C%5C%5C%5C%5Cfrac%7B1%7D%7B5%7D%2A4x%3D%20%5Cfrac%7B1%7D%7B5%7D%2A5%283%2By%29%20%5C%5C%5C%5C%5Cfrac%7B4x%7D%7B5%7D%3D3%2By%5C%5C%5C%5C%5Cfrac%7B4x%7D%7B5%7D%20-3%3D3%2By-3%5C%5C%5C%5C%5Cfrac%7B4x%7D%7B5%7D%20-3%3Dy%2B0%5C%5C%5C%5Cy%3D%5Cfrac%7B4x%7D%7B5%7D%20-3%5C%5C%5C%5Cy%3D%5Cfrac%7B4%7D%7B5%7Dx-3)
so there we have it
![m=\frac{4}{5} \\\\b=-3](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B4%7D%7B5%7D%20%5C%5C%5C%5Cb%3D-3)
T(110) is used to calculate the value of T when w = 110.
<h3>
Linear equation</h3>
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change (slope) and b is the y intercept.
Given the linear equation:
T(w) = 530 - w
Hence T(110) is used to calculate the value of T when w = 110.
