Can you help me please I need it please and can you answer the question and put space in the answers

I.  C

II.  A, D

III.  B

Lines that coincide have infinite solutions, and parallel lines have no solutions.

Step-by-step explanation:

3. To solve this equation, look at the slopes of the equation.  The equations are in y=mx+b form.  m is equal to the slope.

Equations with different slopes will have one solution, meaning that the lines will intersect once.

Equations with the same slope will either have no solutions or infinite solutions.  If the equations are the exact same, it will have infinite solutions, meaning that the line "intersects" itself in infinite places since its basically one line right on top of another.  If the equations have different y-intercepts, it will have no solutions because the lines are going at the same angle, are parallel and will never intersect.

This means that A and D have one solution, B has infinite solutions, and C has no solutions.

4.  Lines that coincide have infinite solutions, and parallel lines have no solutions.

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral
