What does the value of y have to be so that
(7, y) and (6,-5) have a slope of 3 between them?

-2

Step-by-step explanation:

rise over run. if you move 1 unit on the x axis then you must move up three units on the y axis to have a slope of 3

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
