What is the x - intercept of the equation 3x + 4y = 12?y = 3x = 4y = -3x = -4
Question
What is the x - intercept of the equation 3x + 4y = 12?y = 3x = 4y = -3x = -4
Solution
The x-intercept of an equation is the point where the line crosses the x-axis. This happens when y = 0.
So, to find the x-intercept, we set y = 0 in the equation and solve for x.
The equation is 3x + 4y = 12.
Substitute y = 0 into the equation:
3x + 4(0) = 12 3x = 12 x = 12 / 3 x = 4
So, the x-intercept of the equation 3x + 4y = 12 is 4.
