Answer:

The gradient of the graph below is \mathbf{\frac{3}{2} }

Step-by-step explanation:

We need to calculate the gradient of the graph

The gradient of graph is actually slope of the graph.

The slope of graph can be calculated using formula: Slope=\frac{y_2-y_1}{x_2-x_1}

Taking any 2 points on graph i.e

(1,0) and (-1,-3)

We have x_1=1, y_1=0, x_2=-1,y_2=-3

Putting values and finding gradient:

Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{-3-0}{-1-1}\\Slope=\frac{-3}{-2}\\Slope=\frac{3}{2}

So, The gradient of the graph below is \mathbf{\frac{3}{2} }

balu736 [363]

Answer:

(0, -3)

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

<u>Algebra I</u>

  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

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

x - 4y = 12

x - 5y = 15

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

<em>Elimination</em>

  1. Subtract 2 equations:                    y = -3

<u>Step 3: Solve for </u><em><u>x</u></em>

  1. Define original equation:                    x - 4y = 12
  2. Substitute in <em>y</em>:                                     x - 4(-3) = 12
  3. Multiply:                                                x + 12 = 12
  4. Subtract 12 on both sides:                  x = 0
