Find the slope m.
m = (1 - 2)/(3 - (-1))
m = -1/(3 + 1)
m = -1/4
Use the slope and one of the points and plug into the point-slope formula.
y - 1 = (-1/4)(x - 3)
Isolate y.
y - 1 = (-1/4)x + (3/4)
y = (-1/4)x + (3/4) + 1
y = (-1/4)x + (7/4)
Did you follow?
The answer is B, or 2x + 3y - 5 = 0. This is because when you substitute both points in for x and y, you get the values of 0=0, which is true!
D = drinks, p = popcorn
17 + 3.50d + 3.00p
variables : a letter in place of an unknown number : (d and p)
coefficients : the number multiplied by the letter : (3.50 and 3.00)
constants : a lone number, no variables attached : (17)
Answer:
6days
total cost-$66
additional days-5
Step-by-step explanation:
41+5(x-1)=31+7(x-1)
41+5x-5=31+7x-7
36+5x=24+7x
12=2x
x=6
36+30=66
The answer is 2.
The formula for slop is y2-y1/x2-x1
Using this formula we get 12-4/6-2 or 8/4 which simplifies to 2.
Hope this helps!
