You divide 1444 kilometers by 110 kilometers to get x cm.

1444/110 = 13.127

x = 13.127 cm

Slope of -2 through point (5,2)

Sunny_sXe [5.5K]

Answer:

Step-by-step explanation:

Through -3 , -2 slope = -2/3

y1 = -2 & x1 = -3 and m = -2/3

y - y1 = m(x - x1)

y - (-2) = -2/3(x - (-3))

y + 2 = -2/3(x + 3)

Multiply each term by 3

3y + 6 = -2(x + 3)

3y + 6 = -2x - 6

3y = -2x - 6 - 6

3y = -2x - 12

Write an equation of the line with the given slope that contains the given point.

Alchen [17]

Answer:

$y=-2x+12$

Step-by-step explanation:

We can use the point-slope form given by:

$y-y_1=m(x-x_1)$

Where m is the slope and (x₁, y₁) is a point.

So, we will substitute -2 for m and (5, 2) for (x₁, y₁). This gives us:

$y-(2)=-2(x-(5))$

Simplify:

$y-2=-2(x-5)$

Distribute:

$y-2=-2x+10$

Add 2 to both sides. Hence, our equation is:

$y=-2x+12$
