Find an equation of the line passing through the following points (-8, 4) and (-5, -5)

y= -3x-20

Step-by-step explanation:

°First find the gradient between the two points

Gradient= - 3

°Using the formula y= mx+c substitute the gradient into the equation. You'll get something like this: y=-3x+c

°Substitute the point (-8;4) in the above equation. You'll get something like this : 4=-3(-8) +c

°Calculate the value of c. It'll give you c=-20

°Substitute c=-20 in the equation

Final answer is y= - 3x-20

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.
