Find the slope of the line that goes through the following points. A. –1
B. 1
C. –4
D. –7

B) Slope is 1

Step-by-step explanation:

Y² - Y¹ divide by X² - X¹

Plug in: -3 - (-4) divide by 1 - 0

             = 1 divide by 1

             = Slope is 1

both equations and proportions are better.

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
