Express it in slope form

y=(3/2)x + 1

Step-by-step explanation:

use formula y=mx+b

M is slope

B is y intercept

use point (2,4) for Y2 and X2, and point (0,1) for Y1 and X2 to find the slope.

(Y2(4) - Y1(1))/ (X2(2) - X1(0)) =

(4-1)/(2-0)= 3/2 for slope=M

y intercept is just the point found on the y axis (0,1) so it's just 1. B=1

so then plug in the numbers for the variables.

y=(3/2)x + 1

144.50

step-by-step explanation:

21.5 x 13.4=288.10 divide by 2

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
