Part 1.
The slope is found by the change in Y over the change in X.
In the picture they are finding the difference between the X and Y of each point. They have x1 - y1 over x2-y2, when it should be y2-y1 / x2 - x1.
Part 2:
Slope = Change in Y over change in X:
(4 - 6) / (0 - -2) = -2 / 2 = -1
Slope = -1
Using the point (0,4) tells you the Y-intercept, which is the Y value when x is 0. The Y intercept is added to the slope when writing the equation of a line in point slope form.
The equation is y = -x +4
Part 3:
Find two points on the line by replacing X with 0 and solving for Y and then replace Y with 0 and solve for X. This gives you the X and Y intercepts. Once you have those two points, put them on a graph and then draw a straight line through both dots.
Answer:
13:7
Step-by-step explanation:
We see that the ratio from women:children is 13:4.
Therefore, the number of women is 13.
In the ratio comparing men to children we see that it is 7:3.
Therefore, the number of men is 7.
Now we need to compare the number of women to the number of men which is 13:7.
Answer 2 is 12
Step-by-step explanation:
more than 11 is 12
Answer:
The number of gallons of gas Karl used is 15 gallons.
Option (C) is correct.
Step-by-step explanation:
As given
Karl drove 617.3 miles.
For each gallon of gas, the car can travel 41 miles.
i.e
1 gallons = 41 miles
Now find out for the 617.3 miles.
Thus
Therefore the number of gallons of gas Karl used is 15 gallons.
Option (C) is correct.
