Find the slope of the line that passes through the points (9, -2) and (4, 3)

vovikov84 [41]

Answer:

-1

Step-by-step explanation:

Formula: $y=mx+b$

Using two points:

Since we are given the $y$ and $x$ value, what is left is the $m$ and $b$ in the formula, which represent slope and the y-intercept.

Slope

$m$ is slope

Formula: $\frac{y_2-y_1}{x_2-x_1}$

Plug points: $\frac{3-(-2)}{4-9}$

Solve: $\frac{5}{-5}$

Simplify: $\bold{m=-1}$

Therefore, the slope is -1

y-intercept

$b$ is the y-intercept

Plug one of the points and the slope into the formula, solve for b: (4, 3)

$3=-1(4)+b$

$3=-4+b$

$3+4=-4+b+4$

$\bold{b=7}$

Pqrs is a rhombus. If PO= 4 cm and OQ=3cm,then find PQ.(please answer fast)

exis [7]

Answer: 5 cm

Step-by-step explanation:

The diagonals of a rhombus bisect each other in half

PO = OR = 4 cm

So. PR = 8 cm

Similarly,

SO = OQ = 3 cm

So, SQ = 6 cm

To measure side, formula is

a = √p^2 + q^2 / 2

a = √6^2 + 8^2 / 2

a = √36+64 / 2

a = √100 / 2

a = 10/2 = 5 cm
