Using PEMDAS:
7 - 9 x 7 - 3 = 7x
7 - 63 - 3 = 7x
-59 = 7x
/7 /7
-8.43 = x

Solve for x:
-59 = 7 x

-59 = 7 x is equivalent to 7 x = -59:
7 x = -59

Divide both sides of 7 x = -59 by 7:
(7 x)/7 = (-59)/7
7/7 = 1:
Answer: x = (-59)/7

A line passes through the point (6, -8) and has a slope of -3/2

DENIUS [597]

Use y=mx + b, which is slope intercept form

b = y intercept(when x=0)
m = slope

You need to find the y intercept. Use your coordinates and substitute it in the slope intercept equation.

we use (6, -8)

y = mx + b

Then, -8 = -3/2(6) + b

-8 = -9 + b
1 = b

Thus,

y = -3/2x + 1
