Step-by-step explanation:

(arb)4 = 81r24

a4r4b = 81r24

a4 = 81

a = 4√81

a = 3

r4b = r24

4b = 24

b = 6

A coordinate plane with a line passing through (negative 3, 2) and (0, 3)

Arturiano [62]

Let's check

$\\ \sf\longmapsto Slope=m=\dfrac{3-2}{0+3}=\dfrac{1}{3}$

Y intercept is 3✓

Now

let f(x) be y

$\\ \sf\longmapsto y=mx+b$

$\\ \sf\longmapsto y=\dfrac{1}{3}x+3=f(x)\checkmark$

Suppose y varies directly with x and y=-25 when x=5. find y when x=3

zmey [24]

Let y= -5(x) so that if x =5; y = -5(5) = -25; Therefore let x =3; y = -5(3) = -15
