What is the equation of a line that passes through the point (4, 2) and is perpendicular to the line
whose equation is y = 5 -1?

y = -1/5 x + 14/5

Step-by-step explanation:

Take slope of line and because it perpendicular, you flip it and change the sign.

5 ---> -1/5

Use equation of the line: y - y1 = m ( x - x1 )

y - 2 = -1/5 ( x - 4 )

y - 2 = -1/5 x + 4/5

y = -1/5 x + 14/5

answer: are you

step-by-step explanation:

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
