write an equation in slope intercept form of a line that passes through the point (14, 8) and is (a) parallel (v) perpendicular

Answer:

$y-8=-\frac{7}{3} (x-14)$

Step-by-step explanation:

We can write the equation of a line in 3 different forms including slope intercept, point-slope, and standard depending on the information we have. We have a point and a slope from the equation. We will chose point-slope since we have a point and can find the slope.

Point slope: $y-y_1=m(x-x_1)$

We must find the slope using the slope formula.

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

We substitute $x_1=4\\y_1=9$ and $x_2=-3\\y_2=6$

$m=\frac{6-9}{-3-4}$

$m=\frac{6-9}{-3-4}=\frac{-3}{-7} =\frac{3}{7}$

$m\neq \frac{3}{7}$ in our new equation because it is perpendicular to it. This means we will need to change it into its negative reciprocal which is $m=-\frac{7}{3}$ .

We will substitute $m=-\frac{7}{3}$ and $x_1=14\\y_1=8$ .

$y-8=-\frac{7}{3} (x-14)$

This is the equation of the line perpendicular to the equation line through the points given that crosses through (14,8).

The scale of a map is 1 inch: 250 miles. City A is 378 miles from City B. To the nearest tenth, how far is its distance on the m

juin [17]

This is a proportion question. We can express this as an equation where the answer is x:

$\frac{1}{250}$ = $\frac{x}{378}$

From there, you can just cross-multiply and divide to get:

$\frac{1 * 378}{250}$

A tenth of 250 is 25, so this is roughly $\frac{375}{250}$ or $\frac{17}{10}$ , so it'll be approximately 1.7 inches on the map.
