Find the slope and the y-intercept of he line with the equation 2y+x=-6

The slope is -1/2 and  the y intercept is -3

Step-by-step explanation:

To find the slope and the y intercept, we need to get it in the form

y= mx+b  where m is the slope and b is the y intercept

Solve for y

2y+x = -6

Subtract x from each side

2y+x-x = -x-6

2y =-x-6

Divide by 2

2y/2 = -1/2x -6/2

y = -1/2x -3

The slope is -1/2 and  the y intercept is -3

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
