Write an equation for a line with a slope of 2, through (4,-2) in standard form.

The correct answer would be -2x + y = -10

Step-by-step explanation:

To do this, start with point-slope form and input the known values.

y - y1 = m(x - x1)

y + 2 = 2(x - 4)

Now distribute and solve for the constant.

y + 2 = 2(x - 4)

y + 2 = 2x - 8

-2x + y + 2 = -8

-2x + y = -10

answer: 10 turtles

step-by-step explanation: as turtles have four legs so 4.10=40 therefore birds are 4 which sue counted

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
