Q. What is the x-coordinate of the x intercept of the graph 4x−6y=12Show your work here:(0,−2)(3,0)(4,6)There is no x intercept
Set y to 0: To find the x-intercept, we set y to 0 and solve for x. 4x−6(0)=12 4x=12
Divide by 4: Now, we divide both sides of the equation by 4 to solve for x.44x=412x=3
Check solution: We have found the x-coordinate of the x-intercept to be 3. To check for any math errors, we can substitute x back into the original equation to ensure it makes y equal to 0.4(3)−6(0)=1212=12This confirms that our solution is correct.
