Find a point-slope equation for a line containing the given point and having the given slope. 1. (-4, 3), m = -12 2. (-15, 6), m = -3 3. (5, -2), m = -7 4. (3, -5), m = -2 5. (6, -2), m = -5 6. (-5, -2), m = -4 7. (7, 0), m = -3 8. (0, 9), m = -5 9. (5, 1), m = -10

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

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
