Answer:
a-1/4 , b- 0.17, c-2/9
Step-by-step explanation: you have to read the number line carefuly.
Answer:
1
Step-by-step explanation:
The slope of the perpendicular is the negative inverse of the slope of the line.
m = -1 / (-⅓)
m = 3
The slope between the two points is 3, so:
3 = (15 − 6) / (4 − n)
3 (4 − n) = 9
4 − n = 3
n = 1
X + 2 is an absolute value, so -5 becomes 5
5 + 2 = 7
-4 x 7 = -28
The answer is A. -28
Answer:
b
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 )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 1, 2) and (x₂, y₂ ) = (3, 1)
m =
= -
, thus
y = -
x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 1, 2), then
2 =
+ c ⇒ c = 2 -
= 
y = -
x +
← in point- slope form
Multiply through by 4
4y = - x + 7 ( add x to both sides )
x + 4y = 7 → b
