4. the graph of a line in the xy-plane has a constant
rate of change of 3 and contains the point (2,1).
the graph of a second line passes through the
points (2,11) and (8,- 1). if the two lines intersect
at the point (a, b), what is the value of 3a -b?

a: 4
b: 5
c: 6
d: 7

explain the answer

Type the correct answer in the box. consider the system of linear equations below. rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.
