Question

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

Answer 1

Answer:

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

Step-by-step 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
