9x+7y=7 find the slope

-9/7

Step-by-step explanation:

Put the equation into y = mx + b form, by first isolating y:

9x + 7y= 7

7y = -9x + 7

Divide each side by 7:

y = -9/7x + 1

So, -9/7 is the slope.

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

final total: 63
