Answer:

see attached

Explanation:

You want the graph of the equations ...

  • y = -x +5
  • 3x -2y = 6

Intercepts

We find it convenient to put each equation in standard form when we want to find both intercepts.

ax +by = c

has x-intercept c/a and y-intercept c/b.

y = -x +5

Written in standard form the equation is ...

x + y = 5

Then the intercepts are ...

x-intercept = 5/1 = 5, point (5, 0)

y-intercept = 5/1 = 5, point (0, 5)

3x -2y = 6

The intercepts for this line are ...

x-intercept = 6/3 = 2, point (2, 0)

y-intercept = 6/-2 = -3, point (0, -3)

The graphs of these lines are shown in the attachment.

Additional comment

The first equation is written in slope-intercept form, which tells us the y-intercept is 5. That is the constant in the equation.

Of course, the x-intercept is the point where y=0, and the y-intercept is the point where x=0.

The point where the two lines intersect is (3.2, 1.8).
