The pairs of f(x) =-3x+5 can be found by putting value of x and getting f(x).
x=0, f(x)=5
X=-1, f(x) =3+5=8
x=1, f(x)= -3+5=2
So few ordered pairs arw (0,5) ,(1,2),(-1,8) etc.

Good morning,
Answer:
<h2>the number of true false questions : 6</h2><h2>the number of selected response : 4</h2>
Step-by-step explanation:
Let x represent the number of true false questions
and y represent the number of selected response
we have to solve this system to work out the number of each type of question
x+y=10 (1)
2x+3y=24 (2)
(2) - 2×(1) ⇒ y=4
now ,we replace y by 4 in equation (1)
x = 10 - 4 = 6.

Harrys answer would be 8-7, so 1 and Terry's answer would be 11. 1-11 is negative 10
