Answer:

Step-by-step explanation:

1. Find the slope:

7 -3/ 1 + 1 = 4/2 = 2 = m

2. Find b by plugging in the m and one of the points given into y = mx + b

7 = 2 ( 1 ) + b

7 = 2 + b

5 = b

3. Write the equation using the m and the b you just found

y =2 x + 5

What is the area of the figure? The figure is not drawn to scale.thank you ! :)

Rina8888 [55]

Solution

- The formula for finding the area of a triangle is given below:

$\begin{gathered} A=\frac{1}{2}\times b\times h \\ where, \\ b=\text{ The base of the triangle} \\ h=\text{ The perpendicular height} \end{gathered}$

- We have been given:

$\begin{gathered} b=5.4cm \\ h=2cm \end{gathered}$

- Therefore, we can find the area as follows:

$\begin{gathered} A=\frac{1}{2}\times2cm\times5.4cm \\ \\ \therefore A=5.4cm^2 \end{gathered}$

Final Answer

The area is 5.4cm²

A line passes through the point (4,-6) and he a slope -3/4. Which is the equation of the line?

ANEK [815]

Answer:

The equation of the line is 3x + 4y + 12 = 0

Step-by-step explanation:

$given \: that \: the \: line \: passes \: through \: (4 , - 6) \\ and \: has \: the \: slope \: of \: \frac{ - 3}{4} \\ the \: equation \: of \: the \: line \: is \\ y - y1 = m(x - x1) \\ here \: x1 = 4 \: \: \: y1 = - 6 \: \: and \: m = \frac{ - 3}{4} \\ on \: substituting \: the \: values \: in \: formula \\ y - ( - 6) = \frac{ - 3}{4} (x - 4) \\ y + 6 = \frac{ - 3}{4} (x - 4) \\ 4(y + 6) = - 3(x - 4) \\ 4y + 24 = - 3x + 12 \\ 3x + 4y + 24 - 12 = 0 \\ 3x + 4y + 12 = 0$
