How do you find the slope of a line? (Change in Y / Change in X)

1 answer:

8 0

In order to find the slope of a line, u must use the slope formula. Which is (y2-y1/x2-x1). For example if you had a set of coordinates that are (6,4) and (2,8) you would first sub the 8 from4 which gives you 4. The u do the same with 2 and 6 which gives u 4. After that you divide 4 by 4. and your answer is 1

Which number is irrational?<br><br> A.0.3 B. C.0.777... D.0.454545…

Savatey [412]

Each of A, C, and D are rational, so presumably B is the answer here.

A is rational, since $10\times0.3=3$ , so $0.3=\dfrac3{10}$ .

C is also rational. If $x=0.777\ldots$ , then $10x=7.777\ldots$ . This would mean $10x-x=9x=7$ , and so $x=\dfrac79$ .

D is rational by a similar argument. If $x=0.4545\ldots$ , then $100x=45.4545\ldots$ . So, $100x-x=99x=45$ , which means $x=\dfrac{45}{99}=\dfrac5{11}$ .
