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

The relation is a function.
Step-by-step explanation:
As there is only one y-value for every x-value, this is a function
Answer:
a. x=5
Step-by-step explanation:
The Fraction is
10/x=2
The unknown from the fraction is x
We need to find the value of the unknown
10/x=2
Cross product
We have,
10=2x
Divide both sides by 2
10/2=2x/2
5=x
x=5
Answer is a. x=5
Check
10/5=2
