Answer:

y = mx + b

therefore, the equation is y = -2/3x - 1

the -2/3 got the x because it is the slope and if you look at the formula, it tells you.

y-intercept is the starting point (b)

3. What is f(-3) if f(x) = |2x + 1] +5? (1 point) 0 10 12 or -10

kolbaska11 [484]

If $f(x) = |2x+1|+5$ , then $f(-3) = |2(-3)+1|+5$ . You replace all x's in the function with -3.

$\begin{aligned}f(-3) &= |2(-3)+1|+5\\[0.5em]&= |-6+1|+5\\[0.5em]&= |-5|+5\endaligned}$

Finish by evaluating the absolute value and then adding that to the 5 that's behind the absolute value.

Can you finish it from there?
