y=mx+b is the equation of a line;
m=slope , b= y-intercept
m=4 ; so we have : y=4x+b
We are give a set of points which it passes through, we can simply plug them in:
-2 = 4(3)+b (3 is the x and -2 is the y)
We get -2 = 12 +b .... -14=b
our final equation is : y=4x-14
-4/3 is the answer to your question

Answer:
Rajan gets 6 marks more
Step-by-step explanation:
Neerav's marks are (15)(4) +(5)(-2) = 60 -10 = 50.
Rajan's marks are (14)(4) = 56.
Rajan gets 6 more marks than Neerav.
30x^7
Multiply the coefficients (6•5) to get 30, then add the exponents (4+3) to get 7
Hope this helps!
Answer:
y = 2x - 1
Step-by-step explanation:
None of those would be correct, the line on the graph is y = 2x - 1 because the slope of the line is 2 and the y -intercept -1.
You can also check, we know that on the graph the coordinates where the dots are located are: (2,3),(3,5),(4,7) where the first number is x and second is y coordinate.
Check answer:
Let x=2 if this is correct y should be equal to 3 because of the first point (2,3).
y = 2(2)-1 = 4 - 1 = 3
check the other points if you want to confirm.
