Answer:
y = 2x+5
Step-by-step explanation:
rearrange the equation to make y the sof
y = 1/2x - 3
to find gradient of perpendicular line
1/2 ÷ ( - 1 )
y = -2x + c , the replace the coordinates (-3,-1)
y = 2x + 5
Answer:
option c
Step-by-step explanation:
option c is right..
Answer:8,5 recirpoal is 5,8
Step-by-step explanation:
Alright, let's take an example. 1 is less than 2, so we can write it as 1<2. However, if we multiplied both sides by -1 without changing anything else, we get -1<-2, but -1 is greater than -2 because it is less negative, so the correct way of writing it would be -1>-2. Therefore, since a number that is less positive than another becomes less negative (and therefore higher) when both are multiplied by -1, we have to change the side of the inequality
