Hey there!
To start, the slope intercept equation format is y=mx+b where m=the slope and b=the y-intercept.
Because you appear to have a coordinate set to plug in for x and y as well as a slope of 4, you can plug your known values into the slope intercept equation:
y=mx+b
coordinate: (1,6)
y=6 (the y value of the coordinate point)
x=1 (the x value of the coordinate point)
m=4 (the slope of the equation, given)
6=4(1)+b
Because b, your y-intercept is your only missing value, you can simplify your equation and solve for b:
6=4(1)+b
6=4+b
b=2
Now that you have your two needed values, your slope and your y-intercept, your final equation should be y=4x+2, or the third choice.
Hope this helps and I hope you have a wonderful rest of your day! :)
Answer:
Step-by-step explanation:
parallel lines MUST have the same slope :)
so 2
Answer:
The answer is clearly 4 and 1. If we change the sign on 1 (making it -1), then you have the answer to your original question. 4 and -1 multiply to -4 and add up to 3.
Answer:
The answer to your question is 20x + 21y + 14
Step-by-step explanation:
Data
Expression 1/5 (150x - 80y + 50 - 50x - 25y + 20)
Process
1.- Multiply 1/5 by each term
150/5x - 80/5y + 50/5 - 50/5x - 25/5y + 20/5
2.- Simplify
30x - 16y + 10 - 10x - 5y + 4
3.- Simplify like terms
(30x - 10x) + (-16y - 5y) + (10 + 4)
4.- Result
20x + 21y + 14
