Question

Math helpwhat's the equation in function notation​

Answer 1

Answer:

y = 1 , y = x

Step-by-step explanation:

Consider the line with points (0,1) and (2,1)

Slope of a straight line = change in y ÷ change in x

Slope of this line = $\frac{1 - 1}{2 - 0}$ = 0

Taking another point (x,y) on the line;

Slope =  $\frac{y - 1}{x - 2}$ = 0

y - 1 = (x - 2)0

y = 1 (and this is the equation of the line)

Consider the line which passes through points (-1,-1) and (0,0)

Slope = $\frac{0 - - 1}{0 - - 1}$ = 1

Taking another point (x,y) on the line;

slope = $\frac{y - 0}{x - 0}$ = 1

y = x  (and this is the equation of our second line)
