If you look carefully at the graph, you may see that the slope of the line is
          3-4           -1
---------------- = ------ = m
         7-4             3

thus, you have the slope of the line and two points on the line.  Suppose we
choose the point (4,4) and subst. the known slope and the coordinates of this point into the point-slope formula for the eqn of a str line:

y-y1 = m (x-x1)

y-4 = (-1/3)(x-4)

This is the desired equation.  You could, if you wished, change this into slope-intercept form.

Given:

The system of equations is

y=1.5x-3

y=1.5x+4

To find:

The true statement about the given system of equations.

Solution:

The slope intercept form of a line is

y=mx+b

Where, m is the slope and b is the y-intercept.

We have,

y=1.5x-3

y=1.5x+4

On comparing these two lines with slope intercept form, we get

m_1=1.5,b_1=-3

m_2=1.5,b_2=4

Since the slopes of the lines are equal but the y-intercepts are different, therefore, the two lines are parallel and the system has no solution.

Therefore, the correct option is A.
