Answer:
Step-by-step explanation:
As x increases four units from -4 to 0, y decreases four units from 0 to -4
slope m = Δy/Δx = -4/4 = -1
The y intercept is at (0, -4) so b = -4
y = -1x + -4
y = - x - 4
as m is negative, slope is negative

Answer:
15
Step-by-step explanation:
Fiona (F) = Sushi (S)
Malachy (M) = 7 Fiona (F)
M = F + 90
F + 90 = 7F
6F = 90
F (Fiona) = 15
S (Sushi) = 15
check: Malachy (M) = 15 * 7 = 105
M-F = 105 - 15 = 90
Answer:
75
Step-by-step explanation:
Average needed to get grade C = 70
Average = Total Amount / No of Items.
No of items = 4
therefore Total needed = 70 x 4 = 280
current total score = 66.75 + 66 + 72.25 = 205
the fourth test minimum score = 280 - 205 = 75
