Question

Write the equation of the line that includes the point (3,3) and has a slope of 2.

Answer 1

Answer:

y = 2x - 3

Step-by-step explanation:

We are given the slope, m = 2

Our standard formula of a line is y = mx + b, so we can substitute for the x and y values of the point (3, 3). If you did not know, the x-value and the y-value are both 3 because the point (3, 3) = (x, y).

So, our equation looks like this:

3 = (2)(3) + b

We can solve for b:

3 = 6 + b

b = -3

And now we have our equation of a line:

y = 2x - 3
