Answer:
63
Step-by-step explanation:
Step 1: Define
f(x) = -x - 12
f(-5) is x = -5
f(-3) is x = -3
Step 2: Find f(-5)
f(-5) = -(-5) - 12
f(-5) = 5 - 12
f(-5) = -7
Step 3: Find f(-3)
f(-3) = -(-3) - 12
f(-3) = 3 - 12
f(-3) = -9
Step 4: Find f(-5) × f(-3)
-7 × -9

The equation of a line that passes through the point (x1,y1) and has a slope of m is
y-y1=m(x-x1)
given
slope=5
and passes throught (-2,-1) is
-2=x1
-1=y1
y-(-1)=5(x-(-2))
y+1=5(x+2)
