Set up and solve word problems.
This one will require a bit of abstract thinking.
Let's consider a linear equation in standard form: ax + by = c,
where a, b, & c are real numbers.
For what values of a, b, and c:
(a) will the equation ax + by = c, have a positive slope,
(b) will the equation ax + by = c, have a negative slope,
(c) will the equation ax + by = c, have a zero slope,
(d) will the equation ax + by = c, have an undefined slope,
(e) will the equation ax + by = c, have a positive intercept,
(f) will the equation ax + by = c, have a negative intercept,
(g) will the equation ax + by = c, have a zero intercept; means the line goes through the origin.
This should be interesting in that this concept check is actually checking a "concept" rather than an answer to a specific problem.

.

(e) The equation ax + by = c has x-intercept x= . So, x-intercept is positive if and only if > 0. (e) The equation ax + by = c has x-intercept x= . So, x-intercept is negative if and only if < 0. (g) YES.
