Answer:
y=4x
Step-by-step explanation:
The equation of a line is y=mx+b, where m is the slope and b is the y intercept.
The slope formula is Δy/Δx, so using the coordinates (1, 4) and (2, 8), the slope is which equals 4.
The y intercept is 0.
Therefore, the equation is y=4x.
1.75
Step-by-step explanation:
you want to divide 7 and 4, you should get 1.75.
Answer:
13 is the number.
Step-by-step explanation:
Given:
Twice the difference of a number and 9 equals 8.
Let the unknown number be 'x'.
Therefore, as per question:
The difference of 'x' and 9 =
Twice the difference means 2 times the difference. So, we multiply 2 to the difference. Therefore,
Now, the above expression is equal to 8. So, we equate the above expression to 8. This gives,
Solving for 'x', we get:
Using distributive property of addition and distributing 2 inside the bracket. This gives,
Therefore, the unknown number is 13.
Now, we can verify our answer.
Therefore, the answer is correct.
