To find the x-intercept of x + 3y = 2, plug in 0 for y and solve for x:

x + 3y = 2

x + 3(0) = 2

x = 2

The x-intercept is (2,0).

To convert y = 3x - 3 into standard form, subtract 3x from both sides:

y = 3x - 3

-3x + y = -3

Then, plug in 2 for x and solve for y to get your point:

-3x + y = -3

-3(2) + y = -3

-6 + y = -3

y = 3

Your point is (2,3).
