A line is drawn so that it passes through the points (-3,0) and (1.4). What is the slope of the line?

vladimir2022 [97]

Answer: $m=1$

Step-by-step explanation:

For this exercise you can use the following formula for calculate the slope:

$m=\frac{y_2-y_1}{x_2-x_1}$

In this case you know that the given line passes through the points (-3,0) and (1.4). Therefore you can identify that:

$y_2=0\\y_1=4\\\\x_2=-3\\x_1=1$

Then, in order to calculate the slope of this line, you must substitute the coordinates of the points into the formula:

$m=\frac{0-4}{-3-1}$

Finally, evaluating, you get that the slope of this line is the following:

$m=\frac{-4}{-4}\\\\m=1$

the number of grams a woman should eat in a day to maintain her weight is proportional to her weight. a woman weighing 102 pound

vitfil [10]

Given:
grams of fat : 34 grams TO weight of woman : 102 pounds
grams of fat : ? TO weight of woman : 180 pounds

This is a proportion problem: 34 grams to 102 pounds.

We first have to convert a unit of measure to another to maintain uniformity of measure. let us convert pounds to grams:

102 pounds * 453.592 grams / pound = 46,266.384 grams
180 pounds * 453.592 grams / pound = 81,646.560 grams

34 grams to 46,266.384 grams = x grams to 81,646.560 grams

proportion: a:b = c:d where ad = bc

34 grams * 81,646.560 grams = x * 46,266.384 grams
2,775,983.04 grams² = x * 46,266.384 grams
2,775,983.04 grams² ÷ 46,266.384 grams = x
60 grams = x

A woman weighing 180 pounds should eat 60 grams of fat to maintain her weight.
