Draw its graph.

Solution

To find the intercepts of the line given by the equation 5x+3y15=05x + 3y - 15 = 0, follow these steps:

Finding the x-intercept:

The x-intercept occurs where y=0y = 0.

Set y=0y = 0 in the equation: 5x+3(0)15=05x + 3(0) - 15 = 0 5x15=05x - 15 = 0 5x=155x = 15 x=3x = 3

So, the x-intercept is (3,0)(3, 0).

Finding the y-intercept:

The y-intercept occurs where x=0x = 0.

Set x=0x = 0 in the equation: 5(0)+3y15=05(0) + 3y - 15 = 0 3y15=03y - 15 = 0 3y=153y = 15 y=5y = 5

So, the y-intercept is (0,5)(0, 5).

Drawing the Graph:

To graph the line 5x+3y15=05x + 3y - 15 = 0, plot the intercepts (3,0)(3, 0) and (0,5)(0, 5), and draw a straight line through these points.

I'll generate the graph for you.
