Answer:
(0, 19)
Explanation:
Find the equation.
Find the slope:
![m = \frac{\text{rise}}{\text{run}} = (y_2 - y_1)/(x_2 - x_1)](https://img.qammunity.org/2022/formulas/mathematics/high-school/rh63p750r2j05xhfl45nbzas5zqvu0op0j.png)
22-16/1-(-1) = 6/2 = 3
Here's our equation so far:
y = 3x + b
Find b by plugging in one pair of (x,y) coordinates.
22 = 3(1) + b
22 = 3 + b
b = 19
Now we now the equation:
y = 3x + 19
So, the y-intercept is 19.
