Find the equation of a line that passes through the points (2,5) and (2, 12).

y = mx + b, so

y = 7x

Step-by-step explanation:

1. Label the numbers X1, Y1, X2, and Y2

2. Find the slope of the line

3. The slope should be 7x

4. Make part of your equation: y = 7x +

5. Then find out the y-intercept of the line. Since there isn't one, then the equation of the line is y = 7x, or y = 7x + 0

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.
