What is the domain of the relation?

timofeeve [1]

Answer:

-4 ≤ x ≤ 6

Step-by-step explanation:

When we talk of the domain, we are referring to the possible x-values

from the diagram, we can see that we have the x-values at -4 and 6

The dotted line means that -4 and 6 are in the domain

Thus, the two points represent the end and starting point of the domain

Writing this in interval notation, we have the representation as;

-4 ≤ x ≤ 6

lilavasa [31]

Answer:

y = -2x + 1

Step-by-step explanation:

y = mx + b (m is the slope and b is the y-intercept)

y = mx + 1

Equation for slope: $\frac{y1-y2}{x1-x2}$

(0,1) (1,-1)

$\frac{1+1}{0-1}$ = $\frac{2}{-1}$ = -2

y = -2x + 1
