Find the x and y intercepts,then graph?

Question

1.)       5x-2y=10

 

 

 

2.) y=-x-4

 

 

 

 

Answer 1

The x-intercept is the value of x when y=0.  The coordinate of the x-intercept is (x, 0).

The y-intercept is the value of y when x=0.  The coordinate of the y-intercept is (0, y).

 

1)

 

5x - 2y = 10

 

 

x-intercept:

 

5x = 10

 

 x =2

 

x-intercept is (2, 0).

 

 

y-intercept:

 

-2y = 10

 

   y = -5

 

The y-intercept is (0, -5).

 

Since we have an equation of a line, we plot these two points (the intercepts).  Then connect them in a straight line.

 

 

Do the same for question 2.
