y = mx + b, where m = slope, and b = y-intercept.
Since you are not given the y-intercept, you have to solve for it through the equation, y = (4/5)x (which is the slope you are given) + b, and replace x and y with values given, which are (-5,-3)
y = (4/5)x + b
-3 = (4/5)(-5) + b
-3 = -4 + b
1 = b
Then replace b in the first equation to get the answer
y = (4/5)x + 1
Answer:
0.5kg per foot
Step-by-step explanation:
1/3 : 2/3
1 : 2
1 kg is 2 feet
0.5 kg/foot
Number 2 is x> -2 hope this helps a little
