1) Graph f(x) = |x|
Observe that y = 2|x - 2| + 5 = 2f(x) + 5
So, these are the transformation rules that you can use:
2) shift the graph 2 units to the rigth: because |x - 2| is f(x - 2)
3) dilate the function (stretch vertically) multiplying by 2
4) shift the graph 5 units upward: because adding a constant to the function moves the graph upward the same amount of units as the value of the constant.
y = mx + b
slope(m) = -4/5
(10,5)...x = 10 and y = 5
now sub into the formula and find b, the y int
5 = -4/5(10) + b
5 = -40/5 + b
5 = -8 + b
5 + 8 = b
13 = b
so ur perpendicular equation is : y = -4/5x + 13 <===
Hope this helps!
<span>y = 300 - 5x
Standard form:
ax + by = c
</span>y = 300 - 5x
<span>5x + y = 300
Then to find the y-intercept, insert a 0 into the 'x'.
5(0) + y = 300
y = 300
The y-intercept is 300.
To find the x-intercept, insert a 0 into the 'y'.
5x + (0) = 300
5x = 300
x = 60
The x-intercept is 60.</span>
X = 7
y = 10
x + y = 700
7x + 10y = 6400
10x + 10y = 7000
(-) 7x + 10y = 6400
______________
3x = 600
x = 200
200 + y = 700
y = 500
