Help this is my last question can somebody plz b help me?

y = (4/3)x

Step-by-step explanation:

You have to find the y-intercept, b. Do this by substituting in the x and y values into the equation:

12 = (4/3)(9) + b

12 = 12 + b

b = 0

So, y = (4/3)x

Hope that helps! :D

y = 4/3x

y = -3/4x + 1 ⇔ 3x + 4y - 4 = 0

have:

(d): perpendicular to 3x + 4y - 4 = 0

     contains the point (9;12)

=> (d): 4x - 3y + 3.12 - 4.9 = 0 ⇔ 4x - 3y = 0 ⇔ y = 4/3.x

Step-by-step explanation:

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
