Answer:

Step-by-step explanation:

We can find the slope using the equation y2-y1/x2-x1=m. So first, we want to subtract 1 from 10, which is 9.

Then, we subtract -2 from 1, which turns into 1+2, or 3. Then divide 9 by 3, which is 3. The slope is 3.

Hope this helps!

5x+6y=18and 18x-15y=36 parallel or perpendicular

Katen [24]

Answer:

They are neither parallel nor perpendicular, since slope are different and not related by any equation

Step-by-step explanation:

First arrange them according to general equation:

$y = mx + c$

for the first equation :

$5x + 6y = 18 \\ 6y = - 5x + 18 \\ { \boxed{y = - \frac{5}{6} x + 3}}$

for the second equation :

$18x - 15y = 36 \\ 15y = 18x - 36 \\ y = \frac{18}{15} x - \frac{12}{5}$

Write the equation, in slope-intercept form, of a line with an undefined slope and an x-intercept of -7. Type the equation in th

quester [9]

Undefined slope

slope=rise/run
if run=0, we get an undefined slope
means that it does go left or right, only up and down
the equaiton will be x=something
x intercept is -7 so the equation is x=-7

In the right triangle below, tanA = 0.45. What is the approximate length of AB?

garik1379 [7]

In the right triangle ABC wherein AB is the hypotenuse, BC is the opposite and CA is the adjacent tanA=0.45. The approximate length of AB which is the hypotenuse is 22, Opposite (BC) is 9 and Adjacent (CA) is 20. You need to use pythagorean formula in getting the length of AB.

YOUR ANSWER IS (22).
