Graphing 4x3y=124x - 3y = 12 Using Intercepts

To graph the linear equation 4x3y=124x - 3y = 12 using the intercept method, apply the following steps:

Step 1 — Calculate the intercepts. To find the x-intercept, substitute y=0y = 0 to obtain 4x3(0)=124x - 3(0) = 12, which simplifies to 4x=124x = 12 or x=3x = 3, giving (3,0)(3, 0). To find the y-intercept, substitute x=0x = 0 to obtain 4(0)3y=124(0) - 3y = 12, which simplifies to 3y=12-3y = 12 or y=4y = -4, yielding (0,4)(0, -4). Step 2 — Generate a third point. Choose a value such as y=4y = 4. Substitution gives 4x3(4)=124x - 3(4) = 12, simplifying to 4x12=124x - 12 = 12, so 4x=244x = 24 and x=6x = 6. The third point is (6,4)(6, 4). Step 3 — Plot and verify. Plot the coordinates (3,0)(3, 0), (0,4)(0, -4), and (6,4)(6, 4) on a coordinate grid, ensuring that they line up perfectly. Step 4 — Draw the line. Draw a straight line through all three points to fulfill the graphed representation of the equation.
