Answer:
y = -1/5 x + 10
Step-by-step explanation:
The equation of a line in point slope form is expressed as;
y - y0 = m(x-x0)
m is the slope
(x0, y0) is the point on the line
Given the equation y = 5x -1
Slope m = 5
Slope of the line perpendicular to the line will bw M = -1/5
Substitute into the equation
y - 8 = -1/5(x-10)
5(y-8) = -(x-10)
5y - 40 = -x+10
5y = -x+10+40
5y = -x+50
y = -1/5 x + 10
Hence the required equation is y = -1/5 x + 10
Answer:
A) is 1/25
Step-by-step explanation:
Slope is rise over sun, hence... 2/50 (rise/run or length)
Then you simplify... 1/25

Step-by-step explanation:
![\sf{2x + 4(7 - x)}](https://tex.z-dn.net/?f=%20%5Csf%7B2x%20%2B%204%287%20-%20x%29%7D)
Distribute 4 through the parentheses
![\dashrightarrow{ \sf{2x + 28 - 4x}}](https://tex.z-dn.net/?f=%20%5Cdashrightarrow%7B%20%5Csf%7B2x%20%2B%2028%20-%204x%7D%7D)
Collect like terms
![\dashrightarrow{ \sf{2x - 4x + 28}}](https://tex.z-dn.net/?f=%20%5Cdashrightarrow%7B%20%5Csf%7B2x%20-%204x%20%2B%2028%7D%7D)
