Answer:
The answer is -114.
Step-by-step explanation:
You have to substitute x = 6 into the function :
![f(x) = - 4 {x}^{2} +5 x](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%20-%204%20%7Bx%7D%5E%7B2%7D%20%20%2B5%20x)
![f( 6) = - 4 {(6)}^{2} + 5(6)](https://tex.z-dn.net/?f=f%28%206%29%20%3D%20%20-%204%20%7B%286%29%7D%5E%7B2%7D%20%20%2B%205%286%29)
![f(6) = - 4(36) + 30](https://tex.z-dn.net/?f=f%286%29%20%3D%20%20-%204%2836%29%20%2B%2030)
![f(6) = - 144 + 30](https://tex.z-dn.net/?f=f%286%29%20%3D%20%20-%20144%20%2B%2030)
![f(6) = - 114](https://tex.z-dn.net/?f=f%286%29%20%3D%20%20-%20114)

Step-by-step explanation:
Answer:
y = x + 3
Step-by-step explanation:
The equation of a line is y=mx + b, where m is the slope and b is the y-intercept.
In this case, the slope of the line is 1, and the y-intercept (the point where the line crosses the vertical axis) is 3. So you just need to plug in the 3 in place of b.
y = mx + b
m = 1
b = 3
y = x + 3
