Answer:
1(20-x)
Step-by-step explanation:
let the number of correct answers be x

Answer:
y-11 = -x + 14
Step-by-step explanation:
The quickest way to a proper equation here is to use the point-slope form:
y-k = m(x-h). Here x = 14 and y = 11, so:
y-11 = -1(x-14), or y-11 = -x + 14.
In slope-intercept form, that'd be y = -x + 25.
