Please help with all, I’ll mark brainliest as long as you tell me how you got that answer.

function= 2nd,6th

not a function=1st,3rd,4th,5th

Step-by-step explanation:

because in graphing a function, there should only be one y for the x. 2 or more y's in one x is considered as not a function

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system

$75.00

step-by-step explanation:

i = prt

i = 1,5000 * 0.025 * 2

i = 75
