Question

How many solutions will this system of equations have?
y = -3.5x - 3.5
y = -3.5x + 3.5
A.) No solution
B.) Infinite solutions
C.) One solution
D.) Two solutions

Answer 1

if its the same it will be 0=0

Answer 2

or a number equals a number

Answer 3

so what would it be?

Answer 4

If its a number equals a number such as 0=0 it will be infinate
if its a number equaling to a different number such as 1=0 its no solution
if its something equals a number its on solution so x=5

Answer 5

\[-3.5x-3.5=-3.5x-3.5\]

Answer 6

Hint...

different y-intercepts but the same slope...would give you lines like



Look parallel, and since "solutions" come from intersecting lines, and parallel lines never cross, we have no solution.

Answer 7

so D?

Answer 8

ohh wait noo its A
