Answer:
Yes. (see below)
Step-by-step explanation:
First, find the slope of the line. You can do that by using the slope formula:
y2 - y1
m = ----------
x2 - x1
Now, choose any two points from the line to plug in. I'm using the points (0, 3) and (2, 4).
4 - 3
m = ------
2 - 0
1
m = --- = 1/2
2
Now, to simplify your situation, you can use the slope-intercept formula. To use this, you first need to find the slope and y-intercept.
The y-intercept is where the line meets the y-axis, which is (0, 3), so the y-intercept is 3.
Now, plug them in:
y = mx + b
y = 1/2x + 3
To see if a specific point is on this line—which, in this case, is (20, 13), plug them in and simplify to see if it's true:
13 = 1/2 (20) + 3
13 = 10 + 3
13 = 13
This is true, so the point (20, 13) is on this line.
8.722 / (-3.56)
Expand 
by multiplying both numerator and denominator by 1000.
Reduce the fraction to the lowest terms by extracting and cancelling out 178.

= -2.45
When you want to find the slope of the perpendicular line, all you have to do is flip the known slope upside down and make it negative. You know that
slope is 3 and you know
is perpendicular. So, just flip 3 upside down into
and then make it negative,

. If you look at the coordinate grid, you can see that
crosses the y-axis at 4. When you put those into slope-intercept form you get

x + 4.
Answer:
(2x+5)(3x-2)
Step-by-step explanation:
6x²+11x-10
6x²+15x-4x-10
3x(2x+5)-2(2x+5)
(2x+5)(3x-2)
