Hello Savanna
y=3x-4
2x+4y=26
Can we solve it together ? :) Thx
We need to solve y=3x-4 for y
Now let's start solving this by substitute 3x-4 for y in 2x+4y=26
2x+4(3x-4)=26
14x-16=26
Now let's add 16 to both sides
14x-16+16=26+16
14x=42
Divide both sides by 14 so we can find the value for x
14x/14= 42/14
x=3
Good job:) now we find the value of x
We are not done yet.
Let's find the value for y by substitute 3 for x in y=3x-4
y=3x-4
y=(3)(3)-4
y=9-4
y=5
Yeah well done :)
Final answer : x=3 and y=5
(3,5)

Answer: y=-2x+8
Step-by-step explanation:
To find the slope of the line, you would use . With the 2 points we are given , we can plug it into this equation to find the slope.
Now we know the slope is -2. To find the y-intercept, we know that the x value is 0. We are given that one of the points is (0,8). That means 8 is our y-intercept.
The final equation we get is y=-2x+8.
Answer:
y= -2×+8
Step-by-step explanation:
find m(slope)
y2-y1 over x2-x1
substitute using (0,8) and (4,0)
m=-2
y=mx+b
substitute x and y to find b using either (0,8) or (4,0)
0=-2(4) + b
0= -8 +b
0+8= -8+8 +b
8=b
y=-2x+8
x + 2y = –8
How many solutions does this linear system have?
Answer:
Step-by-step explanation:
Y = –x + 4
x + 2y = –8
How many solutions does this linear system have
one solution: (8, 0)
one solution: (0, 8)
no solution
infinite number of solutions
