Question

A line passes through the points (1, 3) and (3, -1) on a coordinate plane. What is the equation of this line in slope-intercept form?

y = [ ] x [ ] [ ]


fill in the [ ].

Answer 1

The answer is Y=-2x+5

Answer 2

y=[-2]x[+][5]

Explanation:

`(-1-3)/(3-1)=(-4)/(2) =-2` m= -2

Using the point (1,3) Find the value of b

3= -2(1)+b

3= -2+b

+2 +2

---------

5=b

y= -2x+5
