Answer:
Slope: 1/4
y-intercept: -12
Explanation:
Slope Intercept Form:
y = mx + b
which;
m = slope
b = y- intercept
Thus,
you can substitute to find the slope and y-intercept.
To Find Slope:
Pick two order pairs:
(-8,-14) (-4,-13)
And use this formula : y₂ - y ₁ / x₂ - x₁
-13 - (-14)/ - 4 -(-8)
1/4
As a result, the slope is 1/4.
Slope : 1/4
We can pick any order pairs to find the y-intercept
I will be using the first one (-8,-14)
- 8 = x
- 14 = y
y = mx + b
-14 = 1/4(-8) + b
- 14 = - 2 + b
- 14 + 2 = -2 + 2 + b
-12 = b
As a result, the y-intercept is -12.
y-Intercept: -12
y = 1/4x-12
