Take the coordinates
Ex.
(-5,-1) and count it on the chart
The first number is your x value and ur second number is ur y
Y= up and down
X= side to side
Answer:
C. 256 in2
Step-by-step explanation:
Your answer will be D
As y = -(x+2)(x-1)
Thus the external negative sign will flip the positive 2 into a negative & negative 1 into a positive; Resulting, y=(x-2)(x+1)
Answer:
y+4 = 9/4(x-3)
Step-by-step explanation:
m=slope and b=y-intercept (probably useful for later on in the school years)
y-y1 = m(x-x1) where m is the slope and (x1,y1) is the point
Substituting in what we know
y--4 = 9/4(x-3)
y+4 = 9/4(x-3)
$20/5 is $4, so for every increase in temperature, it's 4 (1°=$4). So 9*4=36. So your answer is B.
