What is the opposite of -1.4 on a number line

1.4 on a number line

Step-by-step explanation:

Opposite is just the number but mirrored say for instance,the opposite of -2.7 is 2.7 and the opposite of 2.7 is -2.7. Hope this helps let me know if im wrong!!

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

step-by-step explanation:

a'(12.5,11.25)

slope=(y1-y2)/(x1-x2)
