SAT Subject Test Mathematics Level 2

The top base is 3, so the coordinates of the fourth point are (3,4).

The answer is (A).

SLOPE-INTERCEPT FORM

With the topic of slope-intercept form, we move from coordinate geometry that is primarily
geometric into coordinate geometry that is primarily algebraic. Slopes and intercepts are
descriptions of lines and points on the grid, but the processes of finding and/or using slopes and/or
intercepts are generally algebraic processes. There’s no need, for instance, to sketch a diagram for a
question like Example 3.

SLOPE-INTERCEPT FORM

For any equation    in  the form    y   =   mx  +   b:

Example 3

m   =   slope

b   =   y-intercept

1. Which    of  the following   lines   has no  point   of  intersection    with    the line    

(A)

(B)
