(a) m = 
calculate the slope (m) using the ' gradient formula '
m = 
let (x₁, y₁) = (8, 9) and (x₂, y₂) = ( - 2, 4)
m = 
= 
=
(b) y - 9 = (x - 8)
the equation of a line in ' point- slope form ' is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
choose any of the 2 given points for (a, b) → (8, 9)
y - 9 = (x - 8) → " point- slope form"
(c) y = x + 5
the equation of a line in ' slope-intercept form ' is
y = mc + c
where m is the slope and c the y-intercept
expand and simplify the point- slope equation
y - 9 = x - 4
y = x - 4 + 9
y = x + 5 → " slope- intercept form"
Answer:
Step-by-step explanation:
6x-6+35 = 3x+29
6x - 3x = 29-29
3x = 0
x=0
Answer:
Hello I don't know this answer
sorry
Answer:
612 feet
Step-by-step explanation:
LA is located at 330 feet ABOVE SEA LEVEL
Death Valley is located 282 feet BELOW SEA LEVEL
We let the sea level be at 0 (consider a number line).
So,
LA would be at +330 feet
and
Death Valley would be at -282 feet
The elevation change between the two would be the difference:
330 - (-282) = 330 + 282 = 612 feet
The difference in elevation = 612 feet
