Answer:
option C is correct
Step-by-step explanation:
Please refer to the attachment
y = - 7x - 20
the equation of a line in ' slope- intercept form ' is
y = mx + c → (m is the slope and c the y- intercept)
here m = - 7 ⇒ y = - 7x + c
to find c substitute ( - 4 , 8 ) into the equation
8 = 28 + c ⇒ c = 8 - 28 = - 20
y = - 7x - 20 → equation in slope- intercept form
Given:
line C: y = x + 14
line D: y = 3x + 2
(6,20) or (3,11)
line C: y = 6 + 14 = 20 or y = 3 + 14 = 17
line D: y = 3(6) + 2 = 18 + 2 = 20 or y = 3(3) + 2 = 9 + 2 = 11
(6,20), because both lines pass through this point.
Answer:
Step-by-step explanation:
Given 3x-4y=65
Y=4
So 3x-4×4=65
3x-16=65
3x=65+16
X=81/3
X=27
So value of X is 27
