Respuesta :

5x - y + 15 = 0

Step-by-step explanation:

The x-intercept occurs at (-3, 0). The other line also goes through this point and has a slope of m = 5 so the equation of this line is

y = 5x + k

where k is the y-intercept. Since this line goes through (-3, 0), substitute this into our equation and we'll get

0 = 5(-3) + k or k = 15

Our equation then becomes

y = 5x + 15

or in standard form, it is

5x - y + 15 = 0
