We have to find b first:
3 = -3/2(10)+b
3 = -15+b
18 = b
Now right the equation, your slope will be the same one....
Y = -3/2x + 18
Answer:
what are the equations
Step-by-step explanation:
you didnt show the equations
In this we know all three zeros and one point from which the graph pass.
So we will let specific cubic polynomial function of the form

As we know zeros are that point where we will get value of function equal to zero. So it is basically in form

SO in given question zeros are (2 , 0) , (3, 0) and (5,0)
So we can say

So required equation is

Now we have one point (0 , -5) from which graph passes.
So we say at x = 0 , f(x) = -5



So required equation of cubic polynomial is

For finding y - intercept we simply plugin x = 0 in given equation.
As we know at x = 0 , value of function is -5.
So y - intercept is -5.
I think you can plus like 180 plus that or 180 minus butttt it’s bc the angle looks like a “C” so you plus
