Answer:

y = 2x - 10

Step-by-step explanation:

Slope-intercept form is...

y = mx + b

To get the slope, you have to use the formula...

(y2 - y1) / (x2 - x1)

In this case,

y2 = 2

y1 = 10

x2 = 6

x1 = 10

So...

(2 - 10) / (6 - 10)

= -8 / -4 = 2

Therefore, slope is 2

y = 2x + b

Using any of the two x and y value provided, input the values in the equation

(I'm going to use 6,2)

2 = 2(6) + b

2 = 12 + b

b = -12 + 2

b = -10

Put this all together...

y = 2x - 10

Hope this helps :)

Let me know if there are any mistakes!!

A rectangle has sides that measure 2 x + 11 units long and 10 x + 1 units long. What is the expression that represents the perim
HACTEHA [7]

Answer:

(24x + 24) units

Step-by-step explanation:

A rectangle is a shape that has four sides in which all angles are equal and opposite sides are equal and parallel to each other. The perimeter of a rectangle is the sum of all its sides. Since opposite sides are equal, the perimeter is given as:

Perimeter = 2(length + width)

Since the sides of the rectangle are 2 x + 11 units long and 10 x + 1 units long. Hence:

Perimeter = 2(2x + 11 + 10x + 1)

Perimeter = 2(2x + 10x + 11 + 1) = 2(12x + 12)

Perimeter = (24x + 24) units
