Question

Write the equation of a line given point (4, 14) and m = 2.

y =? x +?

Answer 1

Do you know point-slope form?

Answer 2

i think its y =? x +?

Answer 3

it's y=mx+b

Answer 4

y= can be rewritten as f(x) for future purposes

Answer 5

mx is your slope and b is your y intercept

Answer 6

So you're given m, it's 2.
y=2x+b

Answer 7

Now, to find b, you input the point for (x, y)

Answer 8

So, 14=2*4+b
solve for b

Answer 9

b=6?
