Find the equation of the line shown.

Ymorist [56]

Answer:

y= -2x+9

Step-by-step explanation:

The equation will be written this way :

y= m*x+c

m is the slope
c is a constant
m =( f(4)-f(2))/(4-2)=(1-5)/2= -4/2 = -2
y = -2x+c
replace x and y by the coordinates of a point to get c
1= -2*4+c
c = 9

y = -2x+9

Cancel the common factor of the numerator and the denominator and write specified expression

lisabon 2012 [21]

Step-by-step explanation:

Hello,

I hope you mean to cancel the common factor that exists in numerator and denominator,right.

so, Let's look for the common factor, 

here, the expression is, 

=4(x-2)/ (x+5)(x-2)

so, here we find the common factor is (x-2)

now, we have to cancel it. And after cancelling we get,

=4/(x+5)

Note:{ we cancel the common factor if the common factors are in multiply form.}

Hope it helps
