Question

How do I solve this?
Write an equation of a line that passes through the point (0, 4) and whose slope is 4.
Answer

y = x + 4

y = 4x + 4

y = x – 4

y = x

Answer 1

If its a line you know it will be of the form $$y=mx+b$$ Where the slope is m

Answer 2

Sense you know its slope and you have a point on the line, you can solve for b. Thus you will have m and b, and you can completely determine an equation for representing the line.

Answer 3

$$y=4x+b$$
$$4=4\times 0 +b$$
$$4=b$$

Answer 4

So we have $$y=4x+4$$ And its the second one.
