Answer:
Step-by-step explanation:
Number words Nebi has typed = 250
t = Duration of typing = 3 minutes
Number of words typed in 3 minutes = 150
Rate of typing in 3 minutes
So the linear equation representing the situation would be
Where
w = Number of words
m = Number of minutes after starting the timer
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
