(5,1)(-3,4)
slope = (4 - 1) / (-3 - 5) = -3/8
y - y1 = m(x - x1)
slope(m) = -3/8
(5,1)...x1 = 5 and y1 = 1
now we sub
y - 1 = -3/8(x - 5) <=== point slope form
y - 1 = -3/8(x - 5)
y - 1 = -3/8x + 15/8
y = -3/8x + 15/8 + 1
y = -3/8x + 15/8 + 8/8
y = -3/8x + 23/8 <=== slope intercept form
y = -3/8x + 23/8
3/8x + y = 23/8 ...multiply everything by 8
3x + 8y = 23 <==== standard form
8x + 6y = 10 ----------- (1)
5x - 3y = 2.2 ---------- (2)
(2) x 2:
10 x - 6y = 4.4 --------(2a)
(2a) + (1)
18x = 14.4
x = 1.8 ------- sub into (1)
8 (1.8) + 6y = 10
14.4 + 6y = 10
6y = 10 - 14.4
6y = - 4.4
y = - 0.73
There is 1 set of solution to it. (Answer C)
Step-by-step explanation:
since the coefficient is the same for the fist three they have the same equation.
the reason: there can only be one line that goes through one point with a specific coefficient.
15 Im sure its 15 I re calculated just to be sure
Answer:
They get .83 cup per.
Step-by-step explanation:
Divide 6 by 5. So do 6 / 5, which gets you 0.833333333
