Answer:y=-0.75x-1
Step-by-step explanation:firstly find gradient then use one coordinate and substitute for x and y to get the y intercept (c)
Answer:
y=-2x-3
Step-by-step explanation:
Since the slope is -2, we can make an equation : y=-2x+b
Now plug in the point given to find b.
1=-2(-2)+b
1=4+b
b=-3
so, the equation is y=-2x-3
Answer:
14x-85
Step-by-step explanation:
The area of the shaded region is

which if you use the identities to expand it gives you

This then reduces to be
