  1. Find the slope and yintercept of the line: 5x 7y = 14 Sep 1612:55 PM

x and y intercepts

Oct 218:06 PM The yintercept of a line is the point at which the line crosses the y axis. ( i.e. where the x value equals 0 ) y intercept = ( 0, y ) Oct 218:24 PM The xintercept of a line is the point at which the line crosses the x axis. ( i.e. where the y value equals 0 ) x intercept = ( x , 0 )

Find the x and y intercepts of the graph.

Oct 218:34 PM

Find the x and y intercepts of the graph.

Oct 228:00 AM To solve for xintercept: substitute in 0 for y and solve for x

To solve for yintercept:

substitute in 0 for x and solve for y

Oct 218:07 PM Find the x and y intercepts of the equation 3x + 4y = 12.

Oct 218:19 PM Find the x and y intercepts of the equations

  1. y = 2x + 7 2. 3x = y 1
  2. y = 3/4 x 7 4. 3y = 18
  3. 3y = 2x 9 6. 5x + 4y = 10 Oct 218:19 PM Find the x and y intercepts of the equations
  4. 4x 1/3y = 2 8. y – 6x = 5
  5. 4y – x = 3 10. 4x + 7y = 8
  6. 4x + y = 5 12. x – y = 1

Oct 218:27 PM

What if we want to graph a linear

equation using the x and y

intercepts??

Oct 218:27 PM Graph the equation x + 4y = 8 using the x and y intercepts.
