Question

Find an equation of the line that passes through the point (1, 2) and has slope m = 9.
y =

Answer 1

Hint:

Use y = mx+b

So plug in m = 9 to get

y = mx+b

y = 9x+b

Now plug in the given point (1,2). So plug in x = 1 and y =2

2 = 9*1 + b

Then solve for b

Answer 2

y=41/2+9?

Answer 3

2 = 9*1 + b

2 = 9 + b

2 - 9 = b

-7 = b

b =-7

So the equation is y = 9x - 7

Answer 4

Not sure how you got that.
