Hi Grant.
(3x + 5) + (2x - 9) is what we'll start with. Considering we cannot combine variables with numbers, we can only combine like-terms.
3x + 2x; 5 - 9; we result with: 5x - 4
Now, we are left with (5x - 4) - (4x + 3)
Remember to distribute the negative sign to everything to the right.
(5x - 4) - 4x - 3. We are now able to simplify and solve for our answer.
5x - 4x; -4 - 3; we result with x - 7.
Your answer is A.) x - 7.
I hope this helps!
To form an equation with the given information, we use the formula :
y = mx + b, m being the slope and b being the y-intercept.
Since it is given that the slope is -9/7, we substitute m with -9/7.
y = -9/7x + b
To find b, we will substitute the known coordinates into the equation :
At point (-7 , 4), x = -7, y = 4
4 = -9/7 (-7) + b
4 = 9 + b
b = 4 - 9
b = -5
Now we know that b = -5, we will substitute b = -5 into the equation that we found earlier, y = -9/7 x + b :
y = - 9/7x - 5
To make it more readable, we can multiply the equation by 7:
7y = -9x - 5
7y + 9x + 5 = 0

Answer : 7y + 9x + 5 = 0
