Answer:
The standard form of line is

Step-by-step explanation:
we are given a line
slope=3
so,

y-intercept of -2
so,

now, we can use slope-intercept form of line

now, we can plug values

we can write it in standard form of line


we can subtract both sides by 3x



So, the standard form of line is

9514 1404 393
Answer:
d = 290 -3x
Step-by-step explanation:
For each x feet that Armondo travels toward Bianca, Bianca travels 2x feet toward Armondo. The net effect is that the distance between them decreases by x+2x = 3x feet. The distance starts at 290 feet when x=0, so the distance can be described by ...
d = 290 -3x
A GCF ( Greatest Common Factor) is one factor that can be split evenly between the two numbers you have chosen.
For example, the greatest common factor of 4 and 8 would be 4 because this is the greatest number that can be split evenly with the numbers I have chosen.
I hope this helped.
