Question

What equation represents the line shown on the graphs

Answer 1

y = 2x

Explanation:

x is the x-axis

2 is the slope of the line

So, to verify put value of x = 1, 2, 3 and see value of y in the equation y = 2x

For example,

x = 1, y = 2

x = 2; y = 4

x = 3, y = 6

Answer 2

The equation that represent this line is y = 2x

Explanation:

It is in the form y = mx + b

where mx is the slope and b the y-intercept.

How i got to know that it is y = 2x is that i tried other equations first but didn't work, so i tried y = 2x and it's worked.

y = mx + b

y = 2x and b = 0 which means at 0, continue going up by 2 till the is no space left.

Hopefully this helps!
