The correct Answer is:
To solve the equations \(3x - 2y = 4\) and \(5x - 2y = 0\) graphically, we will follow these steps: ### Step 1: Rewrite the equations in slope-intercept form We will convert both equations into the form \(y = mx + b\) where \(m\) is the slope and \(b\) is the y-intercept. 1. For the first equation \(3x - 2y = 4\): \[ -2y = -3x + 4 \implies y = \frac{3}{2}x - 2 \] 2. For the second equation \(5x - 2y = 0\): \[ -2y = -5x \implies y = \frac{5}{2}x \] ### Step 2: Find points for the first equation To plot the first line, we will find two points by substituting values for \(x\). 1. Let \(x = 0\): \[ y = \frac{3}{2}(0) - 2 = -2 \quad \text{(Point: (0, -2))} \] 2. Let \(y = 7\): \[ 7 = \frac{3}{2}x - 2 \implies \frac{3}{2}x = 9 \implies x = 6 \quad \text{(Point: (6, 7))} \] ### Step 3: Find points for the second equation To plot the second line, we will find two points by substituting values for \(x\). 1. Let \(x = 0\): \[ y = \frac{5}{2}(0) = 0 \quad \text{(Point: (0, 0))} \] 2. Let \(y = 5\): \[ 5 = \frac{5}{2}x \implies x = 2 \quad \text{(Point: (2, 5))} \] ### Step 4: Plot the points on a graph - For the first equation \(3x - 2y = 4\), plot the points \((0, -2)\) and \((6, 7)\). - For the second equation \(5x - 2y = 0\), plot the points \((0, 0)\) and \((2, 5)\). ### Step 5: Draw the lines - Draw a line through the points \((0, -2)\) and \((6, 7)\). - Draw a line through the points \((0, 0)\) and \((2, 5)\). ### Step 6: Analyze the graph - Upon drawing the two lines, observe their slopes. The first line has a slope of \(\frac{3}{2}\) and the second line has a slope of \(\frac{5}{2}\). - Since the slopes are different, the lines will intersect at a point. ### Step 7: Find the point of intersection To find the intersection point, we can set the two equations equal to each other: \[ \frac{3}{2}x - 2 = \frac{5}{2}x \] Solving for \(x\): \[ -2 = \frac{5}{2}x - \frac{3}{2}x \implies -2 = \frac{2}{2}x \implies x = -2 \] Substituting \(x = -2\) back into either equation to find \(y\): \[ y = \frac{5}{2}(-2) = -5 \] ### Final Solution The solution to the system of equations is the point of intersection: \[ \text{Point of intersection: } (-2, -5) \]
