Question

Find an equation of the line having the given slope and containing the given point

m=9, (4,1)

Answer 1

y-y1=m(x-x1)

plug in points for x1 and y1 and slope for m

Answer 2

so how would that look?

Answer 3

where there is an m, put a 9. Where there is an y1 put a 1 where there is an x1 put a 4.

Answer 4

replace m with 9
replace x1 with 4
replace y1 with 1

Answer 5

I don't understand what is so magical about searching and replacing that gives people such a hard time.

Answer 6

9x-4(1)?

Answer 7

you need to call on the powers of merlin

Answer 8

The point they give is (x1,y1) = (4,1)
Therefore x1 is 4
y1 is 1

Therefore
y - y1 = m(x-x1)

IS

y - 1 = 9(x-4)

Answer 9

Just find and replace
