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

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)

    5

true
