Slope = (-3/4); contains the point (12,7)

see explanation

Step-by-step explanation:

Assuming you require the equation of the line

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m = - and (a, b) = (12, 7), thus

y - 7 = - (x - 12) ← in point- slope form

Multiply through by 4

4y - 28 = - 3(x - 12) ← distribute

4y - 28 = - 3x + 36 ( add 3x to both sides )

3x + 4y  - 28 = 36 ( add 28 to both sides )

3x + 4y = 64 ← in standard form
