Answer:
A) a vertical line does not represent a function.
Step-by-step explanation:
For a relation to be a function for each value of
there must be only one value of
. In other words a function is one in which each value in the domain set corresponds to only one value in the range set.
Let us check for this condition in the give choices:
A) a vertical line
A vertical line is given as
which meas it is parallel to y-axis and has infinite number of
values for a single
value.
So, its Not a function
B) 
For the given equation, on plugging in some
value will give a single
value.
So, its a Function
C) a horizontal line
A horizontal line is given as
which meas it is parallel to x-axis and has infinite number of
values giving a single
value.
So, its a Function
D) {(1, 7), (3,7), (5, 7), (7,7)}
For the given set for different
valuesthere is only one
value.
So, its a Function
Jessica is doubling a recipe that calls for 1 1/2 cups of milk. How many cups of milk in total does she need?
2 x 1 1/2 = 3
She needs 3 cups of milk in total.
X+5+2x-2+90=180. combine like terms and solve like a normal algebra problem to find x. if you need to find the answer for a certain angle, plug in the value you got for x into one of the angle equations
Y=-1/3x+4
x2-x1/ y2-y1
(0,4)(2,-2)
2-0/-2-4
1/-3
y-intercept is 4
y=-1/3x+4
