Yes, because 5y-2x=18 and 6x=-4y-10 are both linear equations in the same variables, they form a system of linear equations.
R=17
5(17-2)=75
5(15)=75
75=75
For this case we have that by definition, the slope of a line is given by:

Two points are needed through which the line passes:

Substituting:
Rounding:

Answer:

This would be the equation:
Y= 5/2x+5
