Answer:

Step-by-step explanation:

y = 4x - 4 ......slope here is 4 and y int is -4

y = -4x + 4...slope here is -4 and y int is 4

now we compare our slopes and y int's....

learn these, it helps...

if the slopes are different, and y int's are different, then u have 1 solution.

if the slopes are the same and the y int's different, then u have no solutions

if the slopes are the same and the y int's the same, there are infinite solutions.

so ur answer is : 1 solution
