Answer:
A
Step-by-step explanation:
Plug in values
We know that x=4 and y= -8
just plug in numbers until one is correct
4-4(-8)=36
4+32=36
36=36
the answer is A
Answer:
18
Step-by-step explanation:
y=mx + b
m is the slope.
Therefore, 18 should be the slope
Let the distance of the engineer from the base of the building be x, then
tan 38 = 300/x
x = 300/tan 38 = 300/0.7813 = 383.98
Therefore, the distance from the engineer to the base of the building to the nearest whole foot is 384 feet.
Just connect the dots
the -1 is where it passes through the y axis (up and down line)
the -3 is the slope, so every 1 space it goes over it goes 3 down
