Answer:
The equation of the line will be:
Step-by-step explanation:
Given the points
Finding the slope




We know that the value of y-intercept can be obtained by setting x=0, and solving for y
Here,
at x = 0, the value of y = 0
Thus,
y-intercept = b = 0
We know the slope-intercept form of the line equation is

where m is the slope and b is the y-intercept
now substituting m = 0 and b = 0 in the slope-intercept form
y = mx+b
y = 0(x) + (0)
y = 0+0
y = 0
Therefore, the equation of line will be:

90% of people marry there 7th grade love. since u have read this, u will be told good news tonight. if u don't pass this on nine comments your worst week starts now this isn't fake. apparently if u copy and paste this on ten comments in the next ten minutes you will have the best day of your life tomorrow. you will either get kissed or asked out in the next 53 minutes someone will say i love you
I am unsure about the very last problem but I can help with the first two
1) (y+1)+4
If we combine the numbers 1 and 4, we get +5 and can isolate the numbers from the variable.
This would give us

2) (6*r)*7
remember that we do not have to explicitly state 6*r
Instead, we can write it as 6r
this helps us get rid of the parentheses
now we can write it as

I hope this helps!:)
