what is x - y - 3 = 0 marked on a graph

Question

math

 

Answer 1

Put into slope intercept form

x - y - 3 = 0

x - 3 = y          add y to both sides

 

(3, 0) is a solution. Plot a point on (3, 0)

(0, -3) is a solution. Plot a point on (0, -3)

Draw a line through these two points.

Answer 2

To graph this, it makes it easier if you rearrange the terms to match the form y = mx + b. To do this convert the equation as follows:

 

x-y-3 (+y) = 0 ( +y)

y = x - 3

 

From here, m = 1 and b = -3. Plug in these values and graph as a normal equation, remembering that m is the slope and b is the y-intercept.
