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
