Answers:use x = 0 for y-interceptuse y = 0 for x-intercept
There is not really a way to explain, that is just the formula, memorize it.Finding the y-intercept
3x = 2y + 8
x is 0
2y + 8 = 0
2y = -8
Y-INTERCEPT y = -4Finding the x-intercept
3x = 2y + 8
3x = 8
X- INTERCEPT x = 2 2/3
HOPE THIS HELPS :)
In order to find these answers, we must put the equation into slope-intercept form.
Slope-intercept form has the following equation: Y=mx+b
M is the slope of the equation, and b is the Y-intercept. In this case, we have to isolate the Y variable and solve
So, the M in this case is 7, and the b is .5
So, the slope of the equation is 7, and the Y intercept is .5
solve for x an y
To find the y-intercept of an equation, you need to determine where the equation crosses the y-axis, or, simply put, where .
Plugging into the equation gives us the following:
Therefore, the y-intercept is .
To find the x-intercept of an equation, you need to determine where the equation crosses the x-axis, or, simply put, where .
Plugging in into the equation gives us the following:
There, the x-intercept is .
The X intercept is whatever number that can be plugged in for x that will make the equation equal to zero. +b is the y-intercept.
For example, the X intercept of 3x + 1 = y is -1/3 because when -1/3 is plugged for x, 3 times (-1/3) is -1. -1 + 1 is equal to 0, so the x-intercept is -1/3. The y-intercept is 1 because 1 is where b is in the equation. If there is no number for b, the y-intercept is 0.
To find the y intercept, you cover x and it's coefficient and then divide -20 by 4 to get -5. To find the x intercept, you cover y and it's coefficient and divide 5 by -20 to get -4. So, x = -4 and y= -5
When you have a equation you can easily find the x value and y value which you can assume the x-intercept is (x,0). and y-intercept is (0,y)
Hope this helped.
7! = 7×6×5×4×3×2
3! = 3× 2
as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor
so 7! /(3! ) = 7× 6× 5× 4
= 42 × 20
its b) 840✌✌✌
