The equation of the blue line in slope-intercept form is: y = 2x - 3
Since we are given that the line passes through the point (1, 1), we can plug these values into the equation to solve for `b`, the y-intercept.
1 = (2)(1) - 3 + b
1 = 2 - 3 + b
1 = -1 + b
b = 1 + 1
b = 2
Therefore, the equation of the blue line in slope-intercept form is:
y = 2x + 2
The slope of the line is 2. This means that for every 2 positions you move up vertically, you must also move 1 position to the right horizontally.
When x is 1, y is 1 + (2)(1) = 3
Therefore, the equation of the line in slope-interpret form where y is 1 and x is 1 is:
y = 3
