Step-by-step explanation:
The intercepts can be found by setting one variable to zero and solving for the other.
y-intercept: 30·0 +15y = 90 ⇒ y = 90/15 = 6, point (0, 6)
x-intercept: 30x +15·0 = 90 ⇒ x = 90/30 = 3, point (3, 0)
The graph is easily made by plotting the intercepts and drawing a line through them.

I like to let a graphing calculator do the graphing.
