Check the picture below. So let's use those two points on the line.
bearing in mind that the standard form is also a general form.
standard form for a linear equation means
• all coefficients must be integers, no fractions
• only the constant on the right-hand-side
• all variables on the left-hand-side, sorted
• "x" must not have a negative coefficient

The general equation of a line is
y= ax + b
where a is the slope
So a = -7
So y= -7x + b
But it passes through the point (5, -3)
Substitute the coordinates to calculate b:
So -3 = -7(5) + b
-3 = -35 + b
b= 35-3
b= 32
So the equation of the line of slope -7 and passing through the point (5, -3) is
y= -7x + 32
Answer:
7x + 6 =8x - 6
x= 12
Step-by-step explanation:
- put them equal to each other
- then subtract 8x from both sides
- 7x(-8x) + 6 = 8x(-8x) - 6
- to get -1x
- then subtract 6 from both sides
- you'll get -1x = -12
- then divide -1 to both sides
- then you get x = 12
