Question

What is the equation in point slope form of the line that passes through the point (1 -2)

Answer 1

`y+2=3(x-1)`

Explanation:

The complete question is

What is an equation in point-slope form for the line that passes through the points (1,-2) and has a slope of 3

we know that

The equation of a line in point slope form is equal to

`y-y1=m(x-x1)`

In this problem we have

`m=3\\(x1,y1)=(1,-2)`

substitute

`y-(-2)=3(x-1)`

Remember that

(-1)(-1)=+1

so

`y+2=3(x-1)` ----> equation in point slope form
