70 POINTS! PLEASE HELP! Explain the difference between the following equation formats: Slope-Intercept, Point-Slope and Standard
katrin2010 [14]

Answer and Step-by-step explanation:

1.  slope intercept

2.  point-slope form

3.  standard

Explanation:

1.   A <u>slope intercept form</u> equation is when it's set up as y = m x + b

m = slope  

b = y-intercept

2.   <u>A point-slope form</u> is when a line passes through a point

and the equation is set up as  y −b = m ( x−a)

m = slope

(a, b) A point that the line passes through

3. <u>standard lope form</u> is when the equation is set up as

Ax + By = C

The equation for a parabola has the form y=????x2+????x+cy=ax2+bx+c, where ????a, ????b, and cc are constants and ????≠0a≠0. Fin
d1i1m1o1n [39]

The equation for this parabola satisfies

\begin{cases}a-b+c=9\\9a+3b+c=-19\\16a-4b+c=-12\end{cases}

(in other words, plug in each given point's coordinates (x,y) into the equation y=ax^2+bx+c)

Now,

(a-b+c)-(9a+3b+c)=9-(-19)\implies-8a-4b=28\implies2a+b=-7

(a-b+c)-(16a-4b+c)=9-(-12)\implies-15a+3b=21\implies5a-b=-7

and

(2a+b)+(5a-b)=(-7)+(-7)\implies7a=-14\imples a=-2

2(-2)+b=-7\implies b=-3

(-2)-(-3)+c=9\implies c=8

So the equation of the parabola is

y=-2x^2-3x+8
