First, we find the y-intercept, which in this case is -1, because that's where the line crosses the y-axis.
y = mx + b
Where 'm' is the slope and 'b' is the y-intercept, therefore -1 replaces 'b':
y = mx - 1
Now let's take any two points on the line and find the slope.
m = y2-y1/x2-x1
(0, -1) and (1, 2)
m = (2 + 1)/(1 - 0)
m = 3/1
m = 3
So the slope is 3, plug this in the equation also:
y = 3x - 1
Take a picture of the problem so it's easier for people to figure out the solution.
The answer is 105 degrees! They are alternate exterior which means they are congruent! Also, they form vertical angles when you set them next to each other :)
The answer is 600,000,000
