Question

Select the correct answer. What is the equation of the line that has a slope of 3 and goes through the point (-3,-5)? A. y = 3x + 4 B. y = 3x − 14 C. y = 3x − 4 D. y = 3x + 12

Answer 1

Y=Mx+b
M=3
Now you need b, so plug the x-coordinate and y-coordinate into the x and y in the equation to find the b.
-5=3(-3)+b
-5=-9+b
Add 9 to both sides to isolate the b
-5=-9+b
+9. +9
4=b
So the equation is
Y=3x+4
