Which system of equations has one solution?
On a coordinate plane, 2 lines intersect at one point.
On a coordinate plane, 2 lines are parallel to each other.
On a coordinate plane, a line has a positive slope.

pretty sure its On a coordinate plane, 2 lines intersect at one point.

Step-by-step explanation:

they intersect at one point which means there is only one solution

parallel lines never touch meaning they have no intersection points and no solutions

a line having a positive slope isnt really related to solutions??

im pretty sure its the two lines intersecting at one point answer

$4

step-by-step explanation:

$30×5=$150

$150 minus $130=$20

$20÷5=$4.
