Y-intercept: (0, -1) Point: (5, 3) solve for y=mx+b
Help

y= 4x/5 - 1

Step-by-step explanation:

slope , m=

y= mx + b , let's take (5,3)

then 3= 4(5)/5 + b , b= 3-4 = -1

so y= 4x/5 - 1

c 1 hour

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e

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
