C (1,8) and (4,5). To interpret a system of equations when shown a graph, look for the points at which the two function intersect or meet. in this case they meet at both points (1,8) and (4,5)

Step-by-step explanation:
<u>Step 1: Define Systems</u>
4x + 3y = 37
y = x - 4
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: 4x + 3(x - 4) = 37
- Distribute 3: 4x + 3x - 12 = 37
- Combine like terms: 7x - 12 = 37
- [APE] Add 12 on both sides: 7x = 49
- [DPE] Divide 7 on both sides: x = 7
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define equation: y = x - 4
- Substitute in <em>x</em>: y = 7 - 4
- Subtract: y = 3
