In this question, we need to find the slope and y-intercept.

The standard slope-intercept form is:

y = mx + b

Here, m is the slope that is the difference of y values over x values.

b is y-intercept or the value of y where x is zero.

Now map the given equation with the standard equation, we get

y = mx + b. <=> y = 3/2x

hence,

m = 3/2

b = 0, that means the y-intercept is at origan (0, 0).

Now, simply fecth the values of y by placing the values in the given equation.

for x = 1

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

for x = 2

y = 3/2(x) = 3/2(2) = 3 = (2, 3)

for x = 3

y = 3/2(x) = 3/2(3) = 3/2 = (3, 9/2)

Similarly, you can generate ordered pairs for negative x values and plot the graph. '
