The equation of a line in point-slope form is expressed as:
y = mx + b
- m is the slope of the line
- b is the y-intercept
Given the inequality -2y > 7x + 4, this can also be expressed as:
-2y > 7x + 4
y < -7/2x -4/2
y< -7/2x - 2
This shows that the line will be a dashed line and cuts the y-axis at y= -2
