1. Natalie graphed a system of equations with no solution. What must be true about the
equations of the lines?
a. They have the same slope.
b. They have different y-intercepts.
c. The lines are parallel.
d. All of the above.

d.all of the above

Step-by-step explanation:

System of equations with no solution means that lines are parallel to each other,don have any common point.

Note that two lines are parallel if their slopes are equal and they have different y-intercepts.

So all the alternatives are true.
