Answer:

f(-4) = -2

Step-by-step explanation:

To find f(-4) use the "piece" of the function rule defined for x < -3 (because -4 is less than -3).  That part of the rule says the output (range) value is x + 2, so f(-4) = -4 + 2 = -2.

Answer:

y=-\frac{9}{7}x-2

Step-by-step explanation:

Here, we have to convert the equation to slope-intercept form so we can find the perpendicular slope:

7x-9y=-5

-9y=-5-7x

y=-\frac{5}{9}+\frac{7}{9}x

y=\frac{7}{9}x-\frac{5}{9}

Since our slope is m=\frac{7}{9}, then that means the slope perpendicular to it is m=-\frac{9}{7}.

Now we find our new y-intercept so that the line will pass through the point (-7,7):

y=mx+b

y=-\frac{9}{7}+b

7=-\frac{9}{7}(-7)+b

7=9+b

-2=b

Therefore, the equation of the new line is y=-\frac{9}{7}x-2
