Answer:
y = - 2x + 11
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 )
Rearrange y + 2x = m into this form by subtracting 2x from both sides
y = - 2x + m ← in slope- intercept form
with slope m = - 2
Parallel lines have equal slope, thus
y = - 2x + c ← is the partial equation
To find c substitute (4, 3) into the partial equation
3 = - 8 + c ⇒ c = 3 + 8 = 11
y = - 2x + 11 ← equation of line
So what you would want to do is plot the points in a graph, when you do so you line the points and it will give you a triangle.
So in conclusion it should be, a.) Isosceles
Answer:
$11.45
Step-by-step explanation:
Find the unit rate by dividing the total money by the total gallons.
33.90 / 14. 8 = 2.29 per 1 gallon.
This means 5 gallons will cost 5*2.29 = 11.45
The correct answer would in fact be 52
You could tell because 25 divided by 5.25 is less then 1 and the price per card is about $4.76
