Remember
x^-m=1/(x^m)
u^-3=1/(u^3)
1/(u^3)=1/125
therefor
u^3=125
u=5

x=-3
easy
y=-3-13
y=-16
correct

normally, y is output
(x,y)
chose al second numbers
0,3 are all acceptable
B and D

y=mx+b
m=-3
y=-3x+b
sub point
(x,y)
(1,-2)
-2=-3(1)+b
-2=-3+b
1=b
y=-3x+1

remember (x,y) you keep swtiching those

Answer:

y = [-½]x + [-5]

Step-by-step explanation:

Equation describing how x and y are related can be written in slope-intercept form, y = mx + b.

m = slope = ∆y/∆x

Using two pairs of values from the table, (-2, -4) and (0, -5),

Slope (m) = (-5 - (-4))/(0 - (-2)) = -1/2

m = -½

b = y-intercept = the value of y when x is 0 = -5

b = -5

✔️To write the equation, substitute m = -½ and b = -5 into y = mx + b

Thus:

y = [-½]x + [-5]
