Answer:
y = 6x - 13
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 ) = (2, - 1) and (x₂, y₂ ) = (1, - 7)
m = 
= 
= 6, thus
y = 6x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (1, - 7), then
- 7 = 6 + c ⇒ c = - 7 - 6 = - 13
y = 6x - 13 ← equation of line
Answer:
C.7 weeks
Step-by-step explanation:
Subtract 60 on both sides then you get: 30w=210, then divide both sides and you get w=7, so it'll take 7 weeks
Answer:
Two million two hundred one thousand seven hundred sixty.
Answer:
last option: y = (-2/3)x + 5
Step-by-step explanation:
slope-intercept equation: y = mx + b
where m is the slope and b is the y-intercept
if slope m = -2/3, then y = (-2/3)x + b
if point (3, 3) is on the line, substitute x=3 and y=3 into the equation and solve for b:
3 = (-2/3)3 + b
⇒ 3 = -2 + b
⇒ b = 5
Therefore, equation: y = (-2/3)x + 5
