Lucina is given the equation y+8=−14(x+4) and asked to rewrite the equation in slope-intercept form.

her work is outlined below:

y+8=−14(x+4)

step a: y+8=−14x+4

step b: y+8−8=−14x+4−8

step c: y=−14x−4

at which step, if any, did lucina make a mistake?

4 candies

step-by-step explanation:

7 x 28 = 196

200 - 196 = 4 candies remaining.

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.
