Write the slope-intercept form of the equation of the line described.

1 answer:

7 0

The equation for a line is y=mx+b

m is the slope, so when a line is perpendicular to another line is has a slope which is an opposite reciprocal, so change the -1/2 (the slope of the other line) to 2/1 or just 2

so m=2

now you need to plug in the point they give you for x and y

y=mx+b
4=2(4) + b
simplify
4=8 + b
subtract 8 over
-4 = b

now that you know that slope (m) and the y-intercept (b) you can plug those two numbers into the original equation for the answer

y= 2x -4

Answer:

It is a case of classical probability.

Step-by-step explanation:

Since we are selecting a number between 1 and 100 randomly which is divisible by 14 the only favorable cases are 14,28,42,56,70,84,98 which are 7 cases out of 100 total numbers thus the required probability becomes

$P(E)=\frac{7}{100}=0.07$
