Answer:
y = -5
Step-by-step explanation:
To find the slope , we use
m = (y2-y1)/(x2-x1)
3/2 = (-2-y)/(2-0)
3/2 = (-2-y)/2
Since the denominators are the same, the numerators have to be the same
3 = -2-y
Add 2 to each side
3+2 = -2-y+2
5 = -y
Divide each side by -1
5/-1 = -y/-1
-5 = y
Answer:
Step-by-step explanation:
1) in order to graph the required direct line it needed two points:
2) one of these two points is Y-intercept. According to the condition it is (0;1);
3) in order to find the second point, it is enough to apply the given slope: to start in point (0;1), then to move to the left direction (-5 units, move no. 1), then to move up (+7 units, move no. 2);
4) to graph the line between two points (red line); y= -7/5x +1.
All the details are in the attachment.
Answer:
$200
Step-by-step explanation:
The y-intercept is where the line meets the y-axis (vertical). The line on the graph appears to go through the point (0, 200).
Answer: There are 24 patients who had allergies or ear infections but not both.
Step-by-step explanation:
Since we have given that
Number of patients having ear infections = 9
Number of patients having allergies = 15
We need to find the number of patients had allergies or ear infections, but not both.
According to Venn diagram , we get that
Number of patients had allergies or ear infections is given by

Hence, there are 24 patients who had allergies or ear infections but not both.
