check the picture below.
recall that a flat-line is always 180°, and the sum of all interior angles in a triangle is 180°.
A. The data in the table represent a function. y=x/2. This is seen as for every value of x in the table, y=x/2(half of it). You can show this further by trying this fact on each value.
B. For the original function, when x =8, y=x/2=4
For the function given in this part, when x=8, y=3(8)-10
y=24-10 y=14
This means the relation given in this part has a greater value when x=8
C. When x=80, f(x)=3(80)-10
=240-10
=230
Divide both sides by -3
y + 5 = -15/3
Simplify 15/3 to 5
y + 5 = -5
Subtract 5 from both sides
y = -5 - 5
Simplify -5 - 5 to -10
y = -10
-9/7
which would be -1 2/7, but slope is not done in mixed fractions.
