Question

A) match the graph shown with one of the following equations.

b) which one of the following points lies on the line 3y=2x-1

Answer 1

a) D or E (see below)

b) C (2, 1)

Explanation:

a)

The slope direction indicates a negative value of x

The y-intercept is positive

Therefore, it can't be A, B or C.

It could be option D, but I can't see option E in full, so it may be D if it is y = -x + 3

b) 3y = 2x - 1

y = (2/3)x - (1/3)

Plugging the values of x = 1, 2 or -2 in this gives C (2, 1) as the point on the line
