Find an equation of a line that has a slope 1/4 and Y intercept zero -8 then graft equation using the slope and Y intercept

y = 1/4x - 8

Step-by-step explanation:

So we do not have the capabilities of graphing but I will help you find the equation.

Slope intercept form: y = mx + b

b = y intercept

m = slope

Put your equation together.

y = 1/4x - 8

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
