<span>x-intercept is when y = 0
0 = -1/2x - 2
1/2x = -2
x = -4
x-intercept = (-4,0)
y-intercept is when x = 0
y = -1/2(0) - 2
y = -2
y-intercept = (0, -2)
(note that in the form y = mx+b, b is the y-intercept, so in y = -1/2x - 2, -2 is the y-intercept)
Now to graph, simply plot these two points (-4, 0) and (0, -2) and draw a line between them.
Best of luck!</span>
Answer:
Rounding to the Nearest Integer
The most common type of rounding is to round to the nearest integer. The rule for rounding is simple: look at the digits in the tenth's place (the first digit to the right of the decimal point).
Answer:
Step-by-step explanation:
To analyse a graph you are meant to determine a general trend, relating the results of an experiment to the hypothesis as well as to form. For example you look at all the values in a line graph and you are yo predict one you are to find its common increase or decrease.
If all possible vertical lines will only cross the relation in one place, then the relation is a function.This works because if a vertical line crosses a relation in more than one place it means that there must be two y values corresponding to one x value in that relation.
The answer is D

Answer:
B) Brand 2
Step-by-step explanation:
Brand 1: $10.68 ÷ 12 = 0.89
Brand 2: $9.44 ÷ 16 = 0.59
Brand 3: $15.30 ÷ 18 = 0.85
Brand 4: $21.84 ÷ 24 = 0.91
Brand 5: $20.40 ÷ 30 = 0.68
Least cost per packet is of Brand 2
