with wat?

Answer 3

i cant see sorry

Answer 4

Well, since you're being asked this question I'm sure you've already seen the formula\[y2-y1/x2-x1\]

What this means is if you insert any two coordinates from a straight line (or tangent line) (x1, y1) and (x2, y2), you can find the rate of change of the line, or in other words the slope.

Answer 5

Using what you have, with (4,5) = (x2, y2) and (-2, 2) = (x1, y1),

\[5-2/4-(-2) = 3/4+2=3/6=1/2\]

There's the slope.

Answer 6

Woops! The eqn should be


5−2/[4−(−2)]=3/(4+2)=3/6=1/2

thanks soo much i get it now
