Asystem of three linear equations in three variables is consistent and independent. how many solutions to the system exist?
~none
~one
~three
~infinite

I believe the correct answer is the second option. A system having three linear equations which has 3 variables, consistent and independent will only have one solution. A consistent would have at least one solution. An independent one would have exactly one.

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!

Yeah she/ he needs look how long that is man
