Answer:
a = 6 b= 7
Step-by-step explanation:
4 (b-1) = 3b + 3 substitue for a
4b - 4 = 3b + 3 subtract 4b from both sides
-4 = 3b + 3 - 4b = -4 = -b + 3 combine 3b and (-4b)
-7 = -b divide by -1 for both sides
7 = b
4a = 3 × 7 + 3 substitute for b
4a = 24 combine like terms
a = 6 divide by 4 on both sides
a = 7 -1
a = 6
Answer:
y =
x + 
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 )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 3, 2) and (x₂, y₂ ) = (1, 5)
m =
=
, hence
y =
x + c ← is the partial equation
to find c substitute either of the 2 points into the partial equation
using (1, 5 ), then
5 =
+ c ⇒ c = 5 -
= 
y =
x +
← in slope-intercept form
I believe it is 0.45 miles per minute.
