Question

Which equation represents the line passing through the points (1, 1) and (-2, 13)?
Answer

4x + y = 5

4x - y = 5

x + 4y = 5

x - 4y = 5

Answer 1

the slope is (13-1) / (-2-1) = -4
so the equation is of the form y = -4x + b
- that should narrow the choice

Answer 2

also x=1 , y=1 will satisfy the equation

Answer 3

so value of b can be found
1 = -4 + b
b = 5

y = -4x + 5 is correct

rearrange this to find the correct one in your list

Answer 4

ok?

Answer 5

umm one sec let me try

Answer 6

4x + y = 5 ?

Answer 7

right

Answer 8

yay

Answer 9

lol ok thanks

Answer 10

yw

Answer 11

u could have solved the by plugging in x=1, y=1 and x = -2 y=13 into each equation to see if they fit but thats a bit tedious

Answer 12

- especially if the correct one was the last

Answer 13

Ok thanks for your help
