Answer:
2. m = 1
3. y - (-1) = 5 (x - 4)
4. y = 5x - 21
Step-by-step explanation:
<u>Work for #2</u>
m (slope) = 
m = 
m =
m = 1
<u>Work for #3</u>
y = -1/5x + 3 and through (4, -1)
The slope of a perperndicular line is the negative reciprocal. So, it is 5.
Plug this number into point-slope form. Use the points you were given (4,-1) in the equation as well.
y - y1 = m (x - x1)
y - (-1) = 5 (x - 4)
y + 1 = 5x - 20 (Only if you are supposed to simplify it)
<u>Work for #4</u>
Finish solving the equation
y - (-1) = 5 (x - 4)
y + 1 = 5x - 20
y = 5x - 20 - 1
y = 5x - 21
