Gnom [1K]

Answer:

x=7

Step-by-step explanation:

x-1

3x-5

______

4x-6

4x-6= 7x-27

-4x -4x

___________

-6= 3x-27

+27 +27

____________

21= 3x

divide both 21 and 3x by 3

$\frac{21}{3}$ = $\frac{3x}{3}$

Write an equation in point slope form for the line that passes through one of the following pairs of points. You may choose the

wolverine [178]

(5,1)(-3,4)
slope = (4 - 1) / (-3 - 5) = -3/8

y - y1 = m(x - x1)
slope(m) = -3/8
(5,1)...x1 = 5 and y1 = 1
now we sub
y - 1 = -3/8(x - 5) <=== point slope form

y - 1 = -3/8(x - 5)
y - 1 = -3/8x + 15/8
y = -3/8x + 15/8 + 1
y = -3/8x + 15/8 + 8/8
y = -3/8x + 23/8 <=== slope intercept form

y = -3/8x + 23/8
3/8x + y = 23/8 ...multiply everything by 8
3x + 8y = 23 <==== standard form
