Jeffrey owes his friend $5. how much is jeffrey’s debt?

$5

Step-by-step explanation:

These exercises are about calculating the magnitude of quantities, and for this we use the absolute value. The absolute value or modulus of x, defined as |x|, of a number x is value of x regardless to its sign. This means we will have |x| = x if x is positive, and |x| = −x if x is negative, so our result will be always positive.

Jeffrey’s debt is then |$5|=$5

b

step-by-step explanation:

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

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
