30 points what is the y-intercept of the line with a slope of −4/7 that passes through the point (7,−7/2)? 5 1/2 −1/2 −41/14

Remark

You already know the slope of the line. It is given as -4/7

Now all you have to do is use the point to get the y intercept.

Solution

What you know so far

y = mx + b

y = (-4/7) * x + b

Use the point to find b

-7/2 = (-4/7)7 + b

- 3.5 = - 4 + b              Add 4 to both sides.

-3.5 + 4 = -4 + 4 + b

1/2 = b

So the entire equation is

y = (-4/7)x + 1/2

B <<<<< Answer

300pi

step-by-step explanation:

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
