Answer:
I believe the answer is A.
Step-by-step explanation:
Slope intercept form is y = ax + b, where a is equal to the slope value, and b is equal to the y-intercept.
You have both the slope and y-intercept, which means that all you need to do is plug in the numbers to the equation in order to get your answer!
Let's plug in -7 for a, which gives you y = -7x + b.
Next, we'll plug in the y-intercept, which gives you y = -7x + 9.
Hope this helps!! :)
Answer:
Obi's age is 18 and Oba's age is 9
Step-by-step explanation:
Let Obi's age be x and Oba's age be y
<u><em>Condition 1:</em></u>
x = 2y -----------(1)
<u><em>Condition 2:</em></u>
(x-4) = 3(y-4)
=> x -4 = 3y-12
=> x - 3y = -9 -----(2)
<u><em>Putting eq (1) in (2)</em></u>
2y - 3y = -9
=> -y = -9
=> y = 9
Now,
x = 2y
=> x = 2(9)
=> x= 18
Answer:
The point (2, -1 ) is not on the graph of the line.
Step-by-step explanation:
3x–4y–12=0
3*2 - 4*(-1) - 12= 0
6 + 4 - 12 =0
10 - 12 = 0
- 2 = 0 , false, so the point (2, -1 ) is not on the graph of the line.
