Answer:
<h3>y = - 1/2x - 1/2</h3>
Step-by-step explanation:
Equation of line is y = mx + c
where m is the slope
c is the y intercept
Slope of the line using points
(1, -1) and (-3, 1) is

Equation of the line using point
( 1 , - 1) and slope - 1/2 is

Hope this helps you.
Not sure:((((((( sorrryyyy
Y = -0.4x
1) It is a straight line
2) I passes through the origin (0,0), because the y-intercpet is 0.
3) The slope is negative, so it passes throuh II and III quadrants
4) The magnitude of the slope = 0.4
4) The angle of the line with the negative side of the x-axis is that whose tan is 0.4 => angle = 21.8 °
With all that information you can identify the graph, given that you didn't include the options.
The answer to the question of what I did do not mean that to me I was just saying
