Answer:
y-intercept is 1
Step-by-step explanation:
We need to find the equation of the line first.
<h3>Gradient</h3>The gradient is found using the formula:
So the equation is y = x + c
To find c we need to substitute the value of x and y into the equation:
-1 = + c
-1 = -2 + c
1 = c
And c is the y-intercept so it is 1
