Consider the slopes and y-intercepts of each system of equations.
Choose True or False for each statement.
a. y=x + 6 and y = -x + 5 has only one solution.
b. y- 5 = 4x and y = 4x - 5 has no solution.
c. 2(3x + 4) = y and y = 6x + 5 has only one solution.
d. 9 + y = 6x and 6x - y = 9 has an infinite number
of solutions
