Question

I really dont know this

Answer 1

y = x + 6

Explanation:

The general form of an equation of a line is

y= mx+b

y = slope ·x + y-intercept

Find the slope of the line, m:

-Pick any 2 points on the line, for example lets pick the points (0, 6) and (3, 10)

-Start at any of the points and go towards the other while note the path

start at (0, 6) and to go to (4, 10) we have to

go up (rise) 4 units from 6 to 10 and

go to the right (run) 4 from 0 to 4.

Slope = m = rise/run = 4/4 = 1

m = 1

Find the y-intercept, b:

The y-intercept is where the line intersects the y-axis. By looking at the given graph we can see y-intercept is 6.

b = 6

The equation of our line is

y = x + 6

Answer 2

y=x+6

Explanation:

The gradient of the line is change in y/ change in x

Thus meaning the gradient is 1. (defined as x)

The line crosses through the y-axis on the point (0,6)

So your euqation will be y = (1 - the gradient) x + (interception of y-axis) 6
