How do you solve #y = 4x - 3#, #y = 1# by graphing and classify the system?
See a solution process below:
To solve this by graphing, plot two points for each equation, draw a line through the two points, and note the intersection of the lines for each equation.
Formula 1:
Plot the two points after solving the equation for them, then draw a line through them:
graph{(x^2+(y+3)^2-0.04)((x-1)^2+(y-1)^2-0.04)=0 [-10, 10, -5, 5]
Equation 2:
graph{(y-1)(y-4x+3)((x+2)^2+(y-1)^2-0.04)((x-2)^2+(y-1)^2-0.04)=0 [-10, 10, -5, 5]
Find the intersection of the lines:
graph{x-1)^2+(y-1)^2-0.04)=0 [-10, 10, -5, 5]
The system of equations is regarded as consistent because it shares at least one point.

To solve the system of equations y = 4x - 3 and y = 1 by graphing, you would plot both lines on the coordinate plane. The first line y = 4x - 3 has a slope of 4 and a y-intercept of -3. The second line y = 1 is a horizontal line passing through the y-coordinate 1. The point of intersection between these two lines represents the solution to the system. The system is classified as consistent and independent since it has exactly one solution.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
