Question

Write the equation of the line that passes through (2,4) and has a slope of -1 in point-slope form.

x-4=-1(y-2)
x-2=-1(y-4)
y-2=-1(x-4)
y-4=-1(x-2)

Answer 1

\[\huge\rm y-y_1=m(x-x_1)\] point slope form
where m is slope and passes though (x_1,y_1) ponit

Answer 2

point*

Answer 3

slope intercept form = (y-y1)/(x-x1) = m
m=slope
(x1,y1) - cordinates of given point

so (y-4)/(x-2) = -1
(y-4)=-1(x-2)

Answer 4

that's a formula to find slope
slope intercept form is y=mx+b
