Answer:
y = x + 3
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, 4) and (x₂, y₂ ) = (4, 7)
m = =
= 1, hence
y = x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation.
Using (1, 4), then
4 = 1 + c ⇒ c = 4 - 1 = 3
y = x + 3 ← equation in slope- intercept form
Distance biked before lunch = 1 km (the number is written in mixed fraction)
⇒ Distance biked before lunch =
Distance biked after lunch = 6 km (the number is written in mixed fraction)
⇒ Distance biked after lunch =
We need to determine how much farther does Hallie bike after lunch than before lunch
Extra distance biked after lunch vs. before lunch = -
⇒ Extra distance biked after lunch vs. before lunch =
⇒ Extra distance biked after lunch vs. before lunch =
⇒ Extra distance biked after lunch vs. before lunch = 4 (in mixed fraction)
Hence, Hallie biked 4 km extra after lunch vs. before lunch.
Answer:
We can calculate the price with both sales by multiplying the 75.5 units of money by both percentages (to multiply them, we divide them by 100 first):
75.5 * 0.24 * 0.6 10.8
