Aline passes through (1 1) and (−3 5) . what is the equation of the line in slope-intercept form?
a.) y=-2x-1
b.) y=-x+5
c.) y=-x+2
d.) y=-2x+3

C

Step-by-step explanation:

The best way to solve this is to replace the numbers and solve. The first number in an ordered pair is the x-value and the second is the y-value. So, you are replacing the X in each situation with the first number in these ordered pairs and seeing if the answer is what is the second value.

For A, you get (-2)(1)-1. This equals -3. This is not correct.

For B, you have -1+5, which is 6. This is also incorrect

For C, you have -1+2, which is 1. For the second ordered pair, 3+2. This is also correct.

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
