Answer:
<h3>y = - 1/2x - 1/2</h3>
Step-by-step explanation:
Equation of line is y = mx + c
where m is the slope
c is the y intercept
Slope of the line using points
(1, -1) and (-3, 1) is
![m = \frac{1 + 1}{ - 3 - 1} = - \frac{2}{4} = - \frac{1}{2}](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7B1%20%2B%201%7D%7B%20-%203%20-%201%7D%20%20%3D%20%20-%20%20%5Cfrac%7B2%7D%7B4%7D%20%20%3D%20%20-%20%20%5Cfrac%7B1%7D%7B2%7D%20)
Equation of the line using point
( 1 , - 1) and slope - 1/2 is
![y + 1 = - \frac{1}{2} (x - 1) \\ y + 1 = - \frac{1}{2} x + \frac{1}{2} \\ y = - \frac{ 1}{2} x + \frac{1}{2} - 1 \\ y = - \frac{1}{2} x - \frac{1}{2}](https://tex.z-dn.net/?f=y%20%2B%201%20%3D%20%20-%20%20%5Cfrac%7B1%7D%7B2%7D%20%28x%20-%201%29%20%5C%5C%20y%20%2B%201%20%3D%20%20-%20%20%5Cfrac%7B1%7D%7B2%7D%20x%20%2B%20%20%5Cfrac%7B1%7D%7B2%7D%20%20%5C%5C%20y%20%3D%20%20%20-%20%5Cfrac%7B%201%7D%7B2%7D%20x%20%2B%20%20%5Cfrac%7B1%7D%7B2%7D%20%20-%201%20%5C%5C%20y%20%3D%20%20-%20%20%5Cfrac%7B1%7D%7B2%7D%20x%20-%20%20%5Cfrac%7B1%7D%7B2%7D%20)
Hope this helps you.
Answer:
4y²−38y−20
Step-by-step explanation:
(y−10)(4y+2)
=(y+−10)(4y+2)
=(y)(4y)+(y)(2)+(−10)(4y)+(−10)(2)
=4y²+2y−40y−20
=4y²−38y−20
