Question

Plz can someone help me im really stuck​

Answer 1

Answer:

a. y = -x + 2

b. (2,1)

Step-by-step explanation:

a. Looking at the graph, we can see that the slope is negative

this is because what we have is a falling graph

secondly, the y-intercept is positive

So the correct equation would be a negative value for slope and positive value for y-intercept

so;

y = -x + 2 can be correct

option D

b) What we simply have to do is to make a substitution

Let us look at the point (2,1)

we have x= 2 and y = 1

Thus,

3(1) = 2(2) - 1

3 = 4-1

3 = 3

That means that the point (2,1) lie on the line
