The slope of the line x = 7 is not defined since the line is parallel to the y-axis. Also, for that reason, it cannot have an intercept on the y-axis. The equation of the line is simply:
x = 7

When an equation is in the form y = mx + b, it is known as slope-y-intercept form. Here, m is the slope and b is the y intercept. So, the slope in the equation y = -2x + 7 is -2.
The line 'Y = - 3' has a slope of zero. Any line parallel to it also has a slope of zero. The line parallel to it with a Y-intercept of 7 is: Y = 7
y intercept 7 x intercept 7/3
Divide all terms by -3 then it will be in slope intercept form
If 2x - 3y = 7, -3 y = 7 - 2x or y = (2x - 7)/3, or y = (2/3)x - (7/3). The slope is 2/3 and the y-intercept is -(7/3).
