"a woodworker makes wooden checker boards. her profit is a function of the price she charges. this graph shows her total profits, y, based on the sales price ,x, of each checkerboard. identify any zeros of the function and interpret what the zeros mean in terms of the situation

we know that

zeros of any function f(x) are values of x where f(x)=0

Here , f(x) is profit function

so, f(x)=0 when x=15 and x=70

f(x)=0 means profit is 0

and profit is zero means neither gain nor loss

so, woodworker won't either loss or gain when x=15 and x=70

so, option-BAnswer

none.

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
