Answer: -4
Step-by-step explanation:
If you are given a problem like this with two points, the easiest way to find the slope is using the equation [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex] with points [tex](x_{1}, y_{1})[/tex] and [tex](x_{2}, y_{2})[/tex].
In this problem, by looking at the graph, you can identify the points (0, 10) and (5, -10)
Let's label these numbers:
x1 = 0x2 = 5y1 = 10y2 = -10Now, plug these numbers into the formula above. That gives you [tex]\frac{-10-10}{5-0}[/tex].
-10 - 10 = -20 and 5 - 0 = 5, which gives you a fraction of [tex]\frac{-20}{5}[/tex], which can be simplified down to -4.

Write a Linear Equation in
Point-Slope Form.
m = -5
(-3, – 7)
Answers
==================================
Work Shown:
m = -5 is the slope
(x1,y1) = (-3,-7) is the point the line goes through
Plug this into the point slope form below and simplify.
y - y1 = m(x - x1)
y - (-7) = -5(x - (-3))
y + 7 = -5(x + 3)
Side note: If we solved for y, we'd get y = -5x - 22 showing that -22 is the y intercept.

Find the equation of a line that contains the points (4,−1) and (−1,−4). Write the equation in slope-intercept form, using fractions when required.
Answers
Answer:
y = 3/5x - 17/5
Step-by-step explanation:
slope formula: (y₂ - y₁) / (x₂ - x₁)
First, plug in these values of the two given points.
(-4 - (-1)) / (-1 - 4)
Simplify within the parentheses.
(-4 + 1) / (-1 - 4)
(-3) / (-5)
3/5
This is your slope. Plug this into a standard slope-intercept equation: y = mx + b
To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (-1, -4). Plug in the x and y values into the x and y of the standard equation.
-4 = 3/5(-1) + b
Multiply.
-4 = -3/5 + b
Add 3/5 to both sides. -- To add it easier, convert 4 to a have a denominator of 5.
-20/5 = -3/5 + b
-20/5 + 3/5 = b
-17/5 = b
Now, plug this into your standard equation.
y = 3/5x - 17/5
Check this equation by plugging in the other point you did not use (4, -1)
-1 = 3/5(4) - 17/5
-1 = 12/5 - 17/5
-1 = -5/5
-1 = -1
Your answer is correct!
Hope this helps!
2x-1-(-x+3) = 6-2x SHOW STEPS....DUE TODAY
Answers
Answer:
x=2
Step-by-step explanation:
Simplify both sides of the equation.
2x−1−(−x + 3)=6−2x
(Distribute the Negative Sign)
2x−1 + −1(−x + 3)=6−2x
2x + −1 + −1(−x) + (−1)(3)=6−2x
2x + −1 + x + −3=6−2x
2x + −1 + x + −3=6 + −2x
(Combine Like Terms)
(2x + x) + (−1 + −3)=−2x+6
3x + −4=−2x + 6
3x−4=−2x + 6
Add 2x to both sides.
3x−4 + 2x=−2x + 6 + 2x
5x−4=6
Add 4 to both sides.
5x−4 + 4=6 + 4
5x=10
Divide both sides by 5.
5x/5=10/5
