<u>Algebra I</u>

  • Terms/Coefficients
  • Coordinates (x, y)
  • Solving systems of equations by substitution/elimination

Step-by-step explanation:

<u>Step 1: Define Systems</u>

y = 5x

20x - 4y = 0

<u>Step 2: Solve for </u><em><u>x</u></em>

<em>Substitution</em>

  1. Substitute in <em>y</em> [2nd Equation]:                                                                        20x - 4(5x) = 0
  2. Multiply:                                                                                                             20x - 20x = 0
  3. Combine like terms:                                                                                         0 = 0

Here we see 0 does indeed equal 0.

∴ our systems has an infinite amount of solutions.

PLEASE HELP!!! PLZ!!!

We can use the vertex form
y = a {(x - h)}^{2}  + k
to find the equation of the graph. We know that a is the coefficient, and since the graph opens upwards and is slightly stretched vertically, we know that a is 1/3. On the graph, we see that the vertex of the parabola is at (0,-1). Therefore, h is 0 and k is -1.
Our vertex form equation is
y =  \frac{1}{3} {x}^{2}  - 1
