Here is the graph for one equation in a system of equations: a. Write a second equation for the system so it has infinitely many solutions.

b. Write a second equation whose graph goes through (0,1) so the system has no solutions

c. Write a second equation whose graph goes through (0,2) so the system has one solution at (4,1)

step-by-step explanation:

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
