Answer: look at pic
Step-by-step explanation:
y=mx+b
m:slope
b:y-intercept
m=-1 (slope) given in the question
y=-1x+b
Plug in the given point (-1,-4) then solve for b
-4=-1(-1)+b
b=-5
y=-x-5
then using the x-intercept and y-intercept you could graph the line
y-intercept = b = -5 (0,-5)
x-intercept (plug in y=0)
0=-x-5
x=-5 (-5,0)

Answer:
4a - 3b + 5 = 5
Step-by-step explanation:
Express the ratios in fractional form
=
( cross- multiply )
4a = 3b ( subtract 3b from both sides )
4a - 3b = 0
Then
4a - 3b + 5 = 0 + 5 = 5
