What's the equation for this? (0, 15) and (5, 3)

Question

The original says to find the equation for the line that satisfies the conditions. It's problem 15, and it exactly says, "Passes through (0,15) and (5,3)" Help please?

Answer 1

through (0,15) and (5,3)

has slope =12/-5 = - 2.4

line equation is y -3= (-2.4)(x -5) in point slope form

or

y = -2.4x +15 in slope intercept form

or

12x +5y = 75 in standard form
