Answer: y = +
Step-by-step explanation:
Using the formula for finding equation of a line :
=
From the question:
X1 = 7
X2 = -1
Y1 = -4
Y2 = 2
Substituting into the formula , we have
=
⇒ =
=
4( y + 4) = -3 ( x - 7)
4y + 16 = -3x + 21
4y = - 3x + 21 - 16
4y = - 3x + 5
y = -3x/4 + 5/4
Answer:
y=-3/4x+5/4
Step-by-step explanation:
Answer:
y = - 3x - 7
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 ) = (- 3, 2) and (x₂, y₂ ) = (- 2, - 1)
m = = = - 3, thus
y = - 3x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (- 2, - 1), then
- 1 = 6 + c ⇒ c = - 1 - 6 = - 7
y = - 3x - 7 ← equation in slope- intercept form
1.5 miles/ .6 hours = 2.5 miles per hour
her walking rate is 2.5 miles per hour
d= r * t
4.5 miles = 2.5 * t
divide each side by 3.5
4.5 /2.5 = t
1.8 = t
t = 1.8 hours
11 am - 9 am = 2 hours
She will make it to work on time because 1.8 hours < 2 hours
