Would i use (y² - y¹) / (x² - x¹) or y=mx + b? if possible evens

You would use y2 - y1 / x2 - x1

Since you are trying to find the slope of the line...

Step-by-step explanation:

10.) x-6

12.) -2x-5

14.) 1/4x-1

16.) 2/5x+1

18.) -1/4x+1/4

Step-by-step explanation:

I used y2-y1/x2-x1 and was able to find all of the answers. Also checked them with a graphing calculator :)

Hope this helps!

hiking down a winding trail.

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
