Best ResponseYou've already chosen the best response.1You are given a coordinate of a point where the line passes. So any idea?

Best ResponseYou've already chosen the best response.0ok youre first step would be to look at the slope/gradient. the standard formula for a straight line is y = mx +b where m is the slope/gradient. For a straight line to be parallel to another the two lines must have the same slope. In this case you are looking for a slope of 3 or something in the form of y = 3x +b. That means two of the answers are completely wrong. the next step is to take the point given (1,6) (x,y) and plug them in to corresponding x and y values in the equation the remaining answers and see if they work meaning if you plug in 1 for x into the equation do you come out with 6 for the y value.

Best ResponseYou've already chosen the best response.1@kyle55 Plug a value and check whether you get 6 for y.

Best ResponseYou've already chosen the best response.1Try both of them (b and d). Plug 1 for x and see whether you get 6 for y. If it does it's the equation. :)

Best ResponseYou've already chosen the best response.0then we plug the options in?

Sachintha

Best ResponseYou've already chosen the best response.1Since the gradient is equal to 3 there are two answers (b and d). The line should also go through the point (1,6). So if we plug x=1 for one of the two equations, the one that gets y=6 is the answer.

Best ResponseYou've already chosen the best response.0i plug 1 into x and 6 into y ?

Sachintha

Best ResponseYou've already chosen the best response.1You don't plug in a value for y. You need to only substitute 1 for x. If you get y=6 for the answer, then that's equation of the line satisfying the above conditions.

Best ResponseYou've already chosen the best response.0no you just use the x value and see what number comes out for y if that number matches the y coordinate that you are given then it is correct. for example in this case the correct answer is b. you are given y = 3x +3 and coordinate (1,6) you use the x value (1) in the equation: y= 3*1+3 and see if you get 6 if you do then that equation has a line passing through the coordinate you need.
