Answer:
y = -3x + 1
Explanation:
- Start by picking any two points on the line.
(-1, 4) and (1, -2)
- Now, use the slope formula to find the slope.
m = y^2 - y^1 / x^2 - x^1
m = -2 - 4 / 1 - (-1)
m = -6 / 1 + 1
m = -6/2
m = -3
So, our slope is -3.
- Let's find the y-intercept now using the slope-line equation:
y = mx + b
4 = -3(-1) + b
4 = 3 + b
-3 -3
---------------------
1 = b
- Lastly, let's put our findings into the slope-line equation:
y = mx + b
slope is -3 and y-intercept is 1
y = -3x + 1
