Select all ordered pairs that are solutions of y=3x−1. (1,3)

(3,8)

(7,17)

(10,29)

B and D

Step-by-step explanation:

PLUG AND CHU

if you don't know what that means, you're just placing the values of x and y into the equation

a) 3=3(1)-1 --> 3≠2

b) 8=3(3)-1 --> 8=9-1 --> 8=8

c) 17=3(7)-1 --> 17=21-1 --> 17≠20

d) 29= 3(10)-1 --> 29=30-1 --> 29=29

b) well because you get well

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
