What is an equation of the line that passes through the point (-1, -3) and is perpendicular to the line y=1/2x-7 ? Please help

y = -2x - 5

Step-by-step explanation:

Set the slope of the given equation to the reciprocal  to get a perpendicular slope:

y = 1/2x --> -2x

y = -2x + b will be your current equation. To get b, you must insert the given information: (-1, -3)

-3 = -2 (-1) + b

Solve:

-3 = 2 + b

-2   -2      

-5 = b

Thus your equation would be y = -2x - 5.

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
