Write an equation perpendicular to y = −1/5x + 9 that passes through the point (-2, -2) in slope intercept form. (y = mx + b) What is the perpendicular slope?

y = 5x + 8

m = 5

Step-by-step explanation:

ok so perpendicular means negative reciprocal of the slope so the original slope of the line is -1/5x so the negative reciprocal is 5 (5/1 and the negative undos the negative so it's positive) so now we will use the point (-2, -2) and plug that into the slope intercept form (y = mx+b)

so -2 = 5(-2) + b

5 • -2 = -10 and u add that to the other side so b = 8 so the answer is y = 5x + 8! hope this helps!

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
