Answer:

Explanation:

Let's remember the equation of a line:

y = mx + b

m: slope (we know it's 3)

b: the y-intercept

So far, we have y = 3x + b, now we need to find b.

Replacing y and x for the given points (-3,-5):

-5 = 3*(-3) + b

-5 = -9 + b

b = -5 + 9

b = 4

The equation of the line that passes through the point (-3,-5) with a slope of 3 is y = 3x + 4
