Q. Find the xx-intercept of the line 7x+4y=287x + 4y = 28. Write your answer as an integer or as a simplified proper or improper fraction, not as an ordered pair.
  1. Set yy to 00: To find the x-intercept, we set yy to 00 and solve for xx.7x+4(0)=287x + 4(0) = 287x=287x = 28
  2. Solve for x: Now, we divide both sides of the equation by 77 to solve for xx.\newline7x7=287\frac{7x}{7} = \frac{28}{7}\newlinex=4x = 4
