How do I graph 4x-y 7?

Answer 1

-3

Answer 2

The first step is to decide on the domain: the values of x for which the graph is to be drawn. Then

• select the lowest value of x in that range, substitute that value in the equation and solve for y. Mark the point with coordinates (x, y);
  
• repeat for the highest value of x in the domain;
• select any intermediate value for x (pick one that makes calculations easy) and repeat.

If the three marked points are on the same straight line, join them together. You're done. If not, you've made a mistake somewhere: check your work.

Answer 3

This is a line. When x=0, y=-7. When y=0, x=7/4. Plot those points and draw a line through them.

Answer 4

1) Solve the equation for y.2) Choose some values for x; calculate the corresponding values for y.

3) Plot the x;y pairs in the coordinate system.

4) Connect those points.
