Answer:
![y = \frac{5}{4}x - 1](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B5%7D%7B4%7Dx%20-%201)
Step-by-step explanation:
A line that passes through the point (4,-6) has a slope of 5/-4. Which of the following gives the equation of the line?
With the slope of 5/-4, and the ordered pair (4,-6) :
let m = 5/-4 (slope),
x1 = 4
y1 = -6
We can use those given values into the point-slope formula:
y - y1 = m(x - x1)
Plugging in those values will give you the answer:
y - (-6) =
(x - 4)
Distribute
into the terms inside the parenthesis:
y + 6 =
+ 5
Subtract 6 from both sides to isolate y:
y + 6 - 6 =
+5 - 6
The equation of the line in slope-intercept form is:
Answer:
x=48
y=70
step by step explanation:
In the question,
<em>Si</em><em>nce</em><em> </em><em>the</em><em> </em><em>trian</em><em>gle</em><em> </em><em>two</em><em> </em><em>sides</em><em> of</em><em> the</em><em> </em><em>traingl</em><em>e</em><em> </em><em>is</em><em> </em><em>equal</em><em>,</em><em> </em><em>it</em><em> </em><em>is</em><em> </em><em>an</em><em> </em><em>isosc</em><em>eles</em><em> </em><em>triangle</em><em>.</em>
<em>For</em><em> </em><em>an</em><em> </em><em>isosc</em><em>eles</em><em> triangle</em><em>,</em><em> </em><em>angles </em><em>oppos</em><em>ite</em><em> </em><em>to</em><em> </em><em>eq</em><em>ual</em><em> </em><em>sides</em><em> </em><em>are</em><em> </em><em>equal</em><em>,</em>
<em>Hence</em><em>,</em>
![(x + 7) = 55](https://tex.z-dn.net/?f=%28x%20%2B%207%29%20%3D%2055)
![x = 55 - 7](https://tex.z-dn.net/?f=x%20%3D%2055%20-%207)
![x = 48](https://tex.z-dn.net/?f=x%20%3D%2048)
![y = 180 - (55 + 55)](https://tex.z-dn.net/?f=y%20%3D%20180%20-%20%2855%20%2B%2055%29)
![y = 180- 110](https://tex.z-dn.net/?f=y%20%3D%20180-%20110)
![y = 70](https://tex.z-dn.net/?f=y%20%3D%2070)
![4x-6=2x-2](https://tex.z-dn.net/?f=4x-6%3D2x-2)
You then would eliminate 6, by adding 6 to both sides
![4x=2x+4](https://tex.z-dn.net/?f=4x%3D2x%2B4)
Then you want all of the X's on the same side, so you subtract 2x from both sides.
![2x=4](https://tex.z-dn.net/?f=2x%3D4)
Then to isolate the X, you divide by 2
![2=x](https://tex.z-dn.net/?f=2%3Dx)
The answer is x=2
