Answer:
Step-by-step explanation:
The equation of the line can be written in slope-intercept form, as y = mx + b.
We need to find the slope (m) and the y-intercept (b) of the line, then plug their values into the slope-intercept equation, to find the equation of the line shown.
y-intercept (b) = the point where the line intercepts the y-axis = 4
Using two points on the line, say, (0, 4) and (2, 3):
m = -½.
Substitute m = -½, and b = 4 into y = mx + b.
The equation of the line would be:

Step-by-step explanation:
<u>Step 1: Define Systems</u>
x + 3y = 9
2x - 3y = 3
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Elimination</em>
- Combine equations: 3x = 12
- Divide 3 on both sides: x = 4
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define equation: x + 3y = 9
- Substitute in <em>x</em>: 4 + 3y = 9
- Isolate <em>y</em> term: 3y = 5
- Isolate <em>y</em>: y = 5/3
<u>Step 4: Graph Systems</u>
