Answer:
y = -2x + 1
Step-by-step explanation:
To find slope, you need to use the formula:
m = 
<u><em>Plug in the numbers accordingly:</em></u>
m = 
m = 
<u><em>Simplify:</em></u>
m = -2
<u><em>To find the y-intercept, you need to plug in one of the coordinates (doesn't matter which one) into the equation:</em></u>
Coordinate : (-1, 3)
3 = -2(-1) + b
3 = 2 + b
<u><em>Subtract 2 from both sides:</em></u>
3 = 2 + b
-2 -2
________
1 = b
<u><em>Put it all together:</em></u>
y = -2x + 1
There are infinitely many values for y in this equation.
Linear equations in two variable have infinite VALUES
Answer:
Ben and Jerry's
Step-by-step explanation:
Haagen is $0.36 per oz
B&J is $0.31 per oz
Just divide price by how many oz.
For example, 4.96/16=0.31
Answer:
Area = 144 ft^2
Step-by-step explanation:
Remark
Use the Pythagorean theorem to find the length of the legs. Then multiply them together and divide by 2.
Equations
a^2 + a^2 = c^2
Area = (1/2) * a^2
Givens
c = 24
Solution
Remember that an isosceles triangle has 2 equal sides. Both legs of the triangle are equal to a.
a^2 + a^2 = c^2 Combine
2a^2 = 24^2 Expand
2a^2 = 576 Divide by 2
2a^2/2= 576/2
a^2 = 288 You might just as well leave this. go to area
Area = 1/2 (288)
Answer: Area = 144 ft^2
