4. Which cannot describe a system of linear equations? A.) no solution
B.) exactly two solutions
C.) infinite solutions
D.) exactly one solution​

The is asking to choose among the following choices that cannot describe a system of linear equations and base on the choices, I would say that the correct answer among them is in letter B. exactly two solution, I hope you are satisfied with my answer and feel free to ask for more.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
