The rate of change is -2

Step-by-step explanation:

The slope-intercept form of a linear equation is y = m x + b, where

m is the slope which represents the rate of change
b is the y-intercept which represent the initial value (value y at x = 0)

∵ y = -2x - 1

- The equation in the slope-intersect form, compare it with

the form above

∴ m = -2

∴ b = -1

∵ m represents the rate of change

∴ The rate of change is -2

∵ b represents y at x = 0

∴ The y-intercept is -1

The rate of change is -2

$\frac{mailbox height}{mailbox shadow}$

$\frac{pinetree height}{pinetree shadow}$

$\frac{3}{4.8} = \frac{h}{56}$

1.8<em>h</em> = 3 x 56

4.8<em>h</em> = 168

In triangles DEF and OPQ, ∠D ≅ ∠O, ∠F ≅ ∠Q, and segment DF ≅ segment OQ; this is not sufficient to prove triangles DEF and OPQ congruent through SAS

<h3>What are congruent triangles?</h3>

Two triangles are said to be congruent if they have the same shape, all their corresponding angles as well as sides must also be congruent to each other.

Two triangles are congruent using the side - angle - side congruency if two sides and an included angle of one triangle is congruent to that of another triangle.
