Answer:
J
Step-by-step explanation:
fairly simple x comes before y and in the top right its starts with (2,3) and you can clearly see close to the 0 (1,1)
In order to make b the subject of this equation, we must isolate it on the left side. We can do this by following these steps:

Subtract b from both sides


Subtract P from both sides


Now, we have isolated b, but it is negative. We can fix this by multiplying both sides of the equation by -1.


Which is your final answer.

Answer:
The equation of the line would be y = -1/4x + 2
Step-by-step explanation:
In order to solve this, start by finding the slope of the original line. You can do this by solving for y.
28x - 7y = 9
-7y = -28x + 9
y = 4x - 9/7
Now that we have a slope of 4, we know that the perpendicular slope is -1/4 (since perpendicular lines have opposite and reciprocal slopes). We can use this and the new point in point-slope form to find the equation.
y - y1 = m(x - x1)
y - 1 = -1/4(x - 4)
y - 1 = 1/4x + 1
y = -1/4x + 2
It is in the simplest form you can't divide anything by one really
Answer:
4/9
Step-by-step explanation:
2/3 * 2/3 is 4/9
2/3 of 3 is 2
subtract 2 from that and you get 0
4/9+0=4/9
