Question

How can you write an equation of a line when you are given the slope and a point on the line? Explain

Answer 1

Answer: y = mx + b

m = slope b = y-intercept

Step-by-step explanation:

Say you are given 2 and (-1, 4)

the equation will look like this:

y = 2x + b

Now we fill in the x and y:

4 = 2 (-1) + b

Now we just solve it:

4 = 2 (-1) +b

4 = -2 + b

b = 6
