what is the poit-slope formula?

Question

includes x and y

Answer 1

Point Slope Form

y - y₁= m(x - x₁)

- - - - - - - - - - - - - -

Slope Intercept form

y = mx + b

- - - - - - - - - - s-

Answer 2

point slope formula is not y=mx+b like so many people think. that is called formula for SLOPE. The formula for POINT-SLOPE is (y-y1)=m(x-x1) The number "1" in these mathematical phrases dont have any value, they are just subscripts to let you know which point you are using, so ignore them for now. The "m" in the equation stands for the slope of a line, or rise/run. Let me give you an example. The slope of a line is 5 and this line runs through the point (3,4)
First you need to plug the numbers into the equation.
replace the y1 with 4 and the x1 with 3. Replace m with 5
This is what you should have:
y-4=5(x-3)
This is point slope, because from here you can discover what the actual slope formula is by solving this like an equation
y-4=5(x-3) : Point-Slope form
y-4=5x-15
y=5x-11 : Slope formula


Hope this helps!

Answer 3

The point slope formula is the equation of a line, given the slope and one of the points.

y = ax + b

a = the slope and b = the point.

Answer 4

y=mx+n where m is the slope and n the y intercept.
If you know the slope and one point (a,b)
y-b=m(x-a)

Answer 5

standard:
y=mx+b

intercepts:
x/a+y/b=1

POINT-SLOPE:
y-y(sub 1)=m(x-x(sub 1))
if the given point is (2,3) and slope is -2
then, substitute, it will be:
y-3=-2(x-2)

Answer 6

y=mx+b

Answer 7

y=mX+b
