Step-by-step explanation:
the general slope intercept form is
y = ax + b
a is the slope, b is the y-intercept (when x=0).
1.
is already defined
y = -2x + 6
2.
the slope is expressed as ratio y/x indicating how many units y changes, when x changes a certain amount of units when going from one point to another.
(-3, -5) and (2, 5).
x changes by +5 units (from -3 to 2), y changes by +10 units (from -5 to +5).
so, the slope is 10/5 = 2
that gives us the first part of the equation :
y = 2x + b
we get b by using the coordinates of one of the points as x and y. e.g. (2, 5)
5 = 2×2 + b = 4 + b
1 = b
so, the full line equation is
y = 2x + 1
Answer:
4.9 units
Step-by-step explanation:
Distance between 2 points= sqrt [(x-x)^2 + (y-y)^2
A= -4,2) and B= (1,4)
d = sqrt[(-4-1)^2 + (2-4)^2]
= sqrt (25+4)
= sqrt29
= 4.9 units
Answer:
to find the sale price, you need to find what 34% of 82 is.
82 x 0.34 = 27.88
subtract that from the original price
82 - 27.88 = $54.12
you could also multiply 82 by (1 - .34) to get the same answer
82 x (.66) = $54.12
sale price is $54.12
hope this helps:)
Step-by-step explanation:
First solve the 2 inequalities for x:-
x > 0 or x <= -5
The last choice is the correct one.
