what is the equation of the line in slope form with slope 2/5ths and passes through the point (-4,-7)

2x - 5y= 27.

Step-by-step explanation:

Using the point-slope form of the equation of a line:

y - y1 = m(x - x1)

Here m = 2/5 and (x1, y1) = (-4, -7):

y - (-7) = 2/5(x - (-4))

y + 7 = 2/5x + 8/5

y = 2/5x + 8/5 - 7       Multiply through by 5:

5y = 2x + 8 - 35

5y = 2x - 27

2x - 5y = 27.

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.
