Question

find the equation with the given slope and containing the given point. Slope 3: through (1,2)

Answer 1

you wanna use this: y-y1=m(x-x1)

y-2=3(x-1)

y-2=3x-3

y=3x-1

Answer 2

y-2=3(x-1)*

Answer 3

Plug it into this equation:
(y-y1) = m(x-x1)
As (x1,y1) = (1,2)
and m = 3 as its slope.. =)

Answer 4

the answer says f(x) = 3x-1

Answer 5

but it only has 2 points not 4

Answer 6

the y and the x are ur variables the y1 and x1 are the points they gave u

Answer 7

so y2 and x2 would be just zero?

Answer 8

there is no y2 or x2

Answer 9

so how did they get the answer

Answer 10

y-y1=m(x-x1)
m is the slope
(y1,x1) is the point
so
m=3
y1=2
x1=1
so
y-2=3(x-1)
y-2=3x-3
y-2+2=3x-3+2
y=3x-1

Answer 11

sorry its (x1,y1) not (y1,x1)

Answer 12

oh ok thank u
