First, find the slope (m):
m = (y2 - y1) / (x2 - x1)
m = (-1 - 1) / (0 - 1)
m = -2 / -1
m = 2
Next, plug the slope and one of the points into the slope-intercept form equation (y = mx + b) to solve for the y-intercept (b):
1 = 2(1) + b
1 = 2 + b
b = -1
Therefore, the equation of the line in slope-intercept form is y = 2x - 1.
Write the equation of the line in slope-intercept form.
