Can you please help me with this question

Given :-

To find :-

Solution :-

As we can see that the graph passes through (0,-6) and (3,0) . So using this we can find the slope of the line . As ,

slope = 0 -(-6)/3-0

slope = 6/3

slope = 2

Also we can see that the y intercept is -6 , as it cuts y axis at y = -6 . On using the slope intercept form of the line we have ,

y = mx + c

y = 2x + (-6)

y = 2x - 6

Hence the required answer is y = 2x - 6

its very big question plz make it small
