Need help with this problem

Step-by-step explanation:

Hey there!

The given equation is; y= -3/4x+1...........(i)

The equation of a line which passes through point (9,12) is;

(y-y1) = m2(x-x1)

(y-12) = m2(x-9).................(ii)

From equation (i)

y = -3/4x+1

Slope (m1) = -3/4

As per the condition of perpendicular lines;

m1*m2= -1

-3m2 = -4

Therefore, m2= 4/3.

Putting value of m2 in eqaution (i).

(y-12) = 4/3(x-9)

Therefore, the equation is; y = 4/3x +9.

Hope it helps...

i think you should think about the question and not look online.

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
