With graphing inequalities, will give medal and will give 50 points on separate question to whoever can get them all right. it's only 4 questions so it should be pretty easy for someone who is good at math lol. if you just give me the answers thats fine but i would prefer an explanation.

the answer is d

step-by-step explanation:

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.

tried on you are knowing that we can't leave the picture in the graph ok no problem now you need to send it in the question group
