Question

 A line passes through the point (4, –6) and has a slope of mc011-1.jpg. Which is the equation of the line?

Answer 1

y = mx + b

 

m = -3/4

 

y = (-3/4)x + b

 

Use the given point (4,-6) to find b:

 

-6 = (-3/4)(4) + b

 

-6 = -3 + b

 

b = -3

 

Final equation:

 

y = (-3/4)x - 3
