Question

The graph of a system of parallel lines will have no solutions.

Always

Sometimes

Never


Given the equation 5x + y = 7, which equation below would cause a consistent-independent system?

10x + 2y = 14

-15x - 3y = -6

5x + y = -7

6x + 2y = 7


How many solutions will this system of equations have?

y = -3.5x - 3.5
y = -3.5x + 3.5

No solution

Infinite solutions

One solution

Two solutions

Answer 1

The graph of a system of equations with different slopes will have no solutions.

Always

Sometimes

Never


An inconsistent system of equations is a system with __________.

the same line

parallel lines

intersecting lines and lines that have the same equation

intersecting lines and lines that have the same slope

Answer 2

I dont know abou the second question, but parallel lines dont intercept each other, never.. so a system of parallel lines always have no solution, and for the system
y=-3.5x-3.5
y=-3.5x+3.5
you can see both lines have the same slope -3.5, so they are parallel lines and the system has no solution

Answer 3

that makes sense
