average the numbers and use a variable to figure out the minimum to get a 90.
x = 94
given the linear inequality :
add 2y to both sides we get;
add 12 to both sides of an equation;
divide both sides by 2 we get;
the related equation for the inequality equation  is;
y-intercepts defined as the graph crosses the y-axis.
substitute x =0 in  to solve for y;
y = 6
x-intercepts defined as the graph crosses the x-axis.
substitute value y = 0 to solve for x;
subtract 6 from both sides we get
multiply both sides by 2 we get;
x = -12
now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
