All coordinate pairs that are solutions to the inequality 5x + 9y < 45 are (0,0), (9, 0) and (0, 5)
Given the inequality expression 5x + 9y < 45
In order to get the solution to the inequality, we will first need to get the x and y-intercept of the graph as shown:
The x-intercept of the graph is the point where y =0
5x + 0 < 45
5x < 45
x < 9
One of the coordinate pair is (9, 0)
The y-intercept of the graph is the point where x = 0
5(0) + 9y < 45
9y < 45
y < 45/9
y < 5
One of the coordinate pair is (0, 5)
There is a solution as well at the origin (0,0)
