What is the slope of the graph y= 25+4.5(x-5)

m = 4.5

Step-by-step explanation:

m is the variable for slope (just for validation)

y = 25 + 4.5 (x - 5)

Expand,

y = 25 + 4.5x - 22.5

Collect like terms,

y = 4.5x + 2.5

The slope of the gradient is always the coefficient of x

Therefore, m = 4.5

Hope this helped!! :)

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this
