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

Answer: 39.2 minutes
Step-by-step explanation:
Angela used 56minutes. Brain used 70% of Angela's time which will be 70% of 56.
70/100 × 56 = 39.2 minutes.
Therefore, Brian used 39.2 minutes for the test.
