Question

A line passes through the points (-1, 4)
and (2,-2). What is the equation of this
line?

Answer 1

Answer:

Concept: Equation of Linear Systems

1. We will start by finding the slope with the equation y2-y1/x2-x1
2. Hence: -2-4/2-(-1)= -2
3. So we determined the slope to be -2
4. Now we need to find the y-intercept.
5. Our standard equation is y=mx+b
6. So -2=-2(2)+b
7. b=2
8. So our equation is y= -2x+2
9. Give brainlist

Answer 2

Answer:

Slope =-3

Equation of a line

y-y1=m(x-x1))

y-4=-3(x+1)

y-4=-3x-6

y=-3x-6+4

y=-3x-2
