Answer:

y = 1/3x - 4

Step-by-step explanation:

the line crosses the y-axis at -4

To calculate the gradient of a straight line we choose two points on the line itself. From these two points we calculate: The difference in height (y co-ordinates) ÷ The difference in width (x co-ordinates)

If we take the points (9,-1) and (6,-2), we do:

-1-(-2) = 1

9-6=3

which gives 1/3

Answer:

y = 1/3x - 4

Y- intercept = -4

Slope = 1/3

Step-by-step explanation:

Y intercept is where the line intercepts/passes through the y axis

Slope is how many units it takes HORIZONTALLY (side to side) to go up ONE unit VERTICALLY (up down)

It took the line 3 horizontal units to go up 1 vertical unit. So you divide 1 by 3 which gives you 1/3
