Equation D: y = 6x + 2

How many solutions are there to the given set of equations? (1 point)

No solution
Two solutions
Infinitely many solutions

Answer 1

i dont get it

Answer 2

@Angle

Answer 3

pls help @Angle

Answer 4

No problem. The idea we are using here is that: The place where the two graphed lines touch is the solution.

Answer 5

In the picture I have attached ^
How many times does it look like the red and blue lines touch?

Answer 6

it will never touch? right

Answer 7

exactly!

Answer 8

because it parallel

Answer 9

ok

Answer 10

perfect

so if the number of solutions = how many times it touches

then you know your answer

Answer 11

Also, if u lines have the same slope, they are parallel and will never touch. Unless the y intercepts are also the same in taht case they overlap

Answer 12

ok than you Angle
