It is a straight line equation with no x or y intercepts on the Cartesian plane
Point is not an undefined term. It can be defined as a mathematically precise location, or as the place where two lines intersect.
No, the best fit line need not go through any data point on a graph.
a point
A point.
If the slope is undefined, it is a vertical line. Therefore the equation is x=2.
An graph with an undefined region has a gap somewhere, where the function at that point is not valid. Usually there is a disjoint or a disconnect between the lines of the graph.
The graph is a straight line, with a slope of 40, passing through the point y=50 on the y-axis.
I understand this to mean x = 2. This is the vertical line passing through the (2, 0) or, alternatively, the vertical line passing through the point where x = 2 on the x-axis.
A straight line, passing through the point (0,5) with a gradient of -3.

x=2 means that on a graph, on the x axis, there is a point. Also, since it is just x=2 it means that the slope is undefined, or that there is a line that is going through that point that is perpendicular to the x-axis. So basically there is a line that goes through (2,0) that is parallel to the y-axis.

y = x - 3The graph is a straight line, passing through the point [ y = -3 ] on the y-axis,and having a slope of [ 1 ].

y = -x + 2The graph is a straight line, with [slope = -1], and passing through the point [y=2] on the y-axis.
6 - 4x = 13 So 4x = -7 or x = -7/4 = -1.75 In 1-dimension, the graph would consist of the single point x = -1.75 In 2-dimensions, the graph would consist of the vertical line, passing through x = -1.75 In 3-dimensions, the graph would consist of the plane parallel to the y-z axes and passing through x = -1.75
