What is an equation of the line that passes through the points (1, 2) and (2, -1)?

Mathematics

Alex Ar [27]2 years ago

Answer:

slope(m) = y2 -y1/ x2 - x1

m = -1 - 2/ 2 - 1

m = -3/1 ; m = -3

using the formula y -y1 = m(x - x1)

y - 2 = -3( x -1)

y -2 = -3x +3

collect like terms

3 +2 = y + 3x

y + 3x = 5

y = -3x + 5( y = mx + c)

equation of the line= y = -3x + 5

write the expressions for when you translate the graph of y = |x+2| a) one unit up b) one unit down c) one unit to the left d) o
irina1246 [14]

Hello!

This question is about which values you are changing when you are transforming an equation.

Let's go through the parent function for an absolute value equation and its various transformations.

y=a|b(x-c)|+d

Since we are only looking at horizontal and vertical transformations, we only need to worry about the c and d values.

The c value of a function determines a function's horizontal position, and the d value of a function determines a function's vertical position.

One thing to note here is that the c value is being subtracted from the x value, meaning that if the function is being transformed to the right, you would actually be subtracting that value, while the d value behaves like a normal value, if it is being added, the function is transformed up, and vice versa.

Now that we know this, let's write each expression.

a) y=|x+2|+1

b) y=|x+2|-1

c) y=|x+3|

d) y=|x+1|

Hope this helps!
