Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange x + 5y = 10 into this form
Subtract x from both sides
5y = - x + 10 ( divide all terms by 5 )
y = -
x +2 ← in slope- intercept form
with slope m = - 
• Parallel lines have equal slopes, hence
y = -
x + c ← is the partial equation of the parallel line
To find c substitute (1, 3) into the partial equation
3 = -
+ c ⇒ c = 
y = -
x +
← equation of parallel line

ABC
Step-by-step explanation:
The altitude will be the geometric mean of the lengths, so

. The smaller leg is the hypotenuse of a right triangle sides 4 and

so the usual trig cliche, hypotenuse 8.
Answer: 8
Answer:
(a,b)------>(-1,-7)let
now
m(x-a)=(y-b)
2(x+1)=(y+7)(where m=slope
2x+2=y+7
2x-y=7-2
2x-y=5 is a required equation.
