(7,−8) and (x,-5) with a slope of -3/4
I have to find the value of X

Sagot :

Answer:

we have

slope=(-5--8)/(x-7)

-3/4=3/(x-7)

-3(x-7)=3×4

-3x+21=12

21-12=3x

3x=9

x=9/3=3

Answer:

x = 3

Step-by-step explanation:

slope = [tex]\frac{y_{2} - y_{1} }{x_{2} -x_{1} }[/tex]

Using the your two points the slope = m = [tex]\frac{-8 + 5}{7-x} = \frac{-3}{4}[/tex]

                                                                       [tex]\frac{-3}{7-x} =\frac{-3}{4}[/tex]

Since the numerators are equal, then the denominators must be equal.

So, 7 - x = 4

-x = -3

x = 3
