Hi again :)
We need to solve -3x+4y=12 for x
Let's start by adding -4y to both sides
-3x+4y-4y=12-4y
-3x=-4y+12
x = (-4y+12)/-3
x= 4/3 y -4
Now substitute 4/3 y -4 for x in 1/4 x - 1/3 y =1
1/4 x -1/3 y =1
1/4 (4/3 y -4) -1/3 y =1
Use the distributive property
(1/4)(4/3 y) + (1/4)(-4) -1/3 y =1
1/3 y -1 - 1/3 y =1
Now combine like terms
(1/3y -1/3y) + (-1) =1
= -1
-1 = 1
Now add 1 to both sides
0=2
So there are no Solutions
The answer is C
I hope that's help Will :)

Answer: I'm not going to give out the answers but I'm happy to explain it and help you out if you're still confused. I'm a geometry honors student rn btw just so you know my credentials.
Step-by-step explanation:
To find slope and write it in slope-intercept form you first need to know the equation and what different variables represent.
y = mx + b is the equation for slope-intercept. You need to find what m and b are to right a slope-intercept equation. for example the first problem's answer is y =
x + 1
m is slope which is the angle that the line is at. To find slope or m, you need to choose a point on the graph. Then, count the amount of spaces vertically and horizontally until the next point on the graph. When I say point, I'm referring to a place on the graph where the line cross perfectly over the intersection of two lines on the graph. Slope is always 'rise over run' meaning it is a fraction containing the amount up or down, over the amount left or right. For example, the first problem (the one on the top left) the slope is
.
b is the y-intercept. The y intercept where the line crosses the y-axis which is that bold line going up and down in the middle. For example in number one, the y-intercept is 1 because it is one unit up from the origin. (the origin is 0,0, or the very middle of the graph).
Hope this helps! :)
Answer:
a
Step-by-step explanation:
x+2y=-10
-x -x
2y=-10-x
y=(1/2)x-5
This is one of the lines and reduces the options to a or c.
3x-y=12
-3x -3x
-y=12-3x
y=3x-12
This is the line with the positive slope and since both lines match, the answer is a.
