P what equation in slope-intercept form represents the line that passes through the points (3,5) and (-9,2)

ivanzaharov [21]

Answer:

$y =\frac{1}{5}x+\frac{22}{5}$

Step-by-step explanation:

To write the equation of a line, use the slope formula to first find the slope.

$m=\frac{y_2-y_1}{x_2-x_1}=\frac{5-2}{3--9}=\frac{3}{3+12}=\frac{3}{15}=\frac{1}{5}$

Substitute m=1/5 and the point (3,5) into point slope formula.

$y-y_1 = m(x-x_1)\\y-5=\frac{1}{5}(x-3)\\y-5=\frac{1}{5}x -\frac{3}{5}\\y =\frac{1}{5}x+\frac{22}{5}$

The picture. and answer 1-6. please hurry

satela [25.4K]

Answer:

Step-by-step explanation:

From the figure attached,

1). Sin(D) = $\frac{\text{Opposite side}}{\text{Hypotenuse}}$

= $\frac{EF}{DF}$

= $\frac{24}{26}$

= $\frac{12}{13}$

2). Cos(D) = $\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

= $\frac{ED}{DF}$

= $\frac{10}{26}$

= $\frac{5}{13}$

3). tan(D) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

= $\frac{EF}{DE}$

= $\frac{24}{10}$

= $\frac{12}{5}$

4). sin(F) = $\frac{\text{Opposite side}}{\text{Hypotenuse}}$

= $\frac{DE}{DF}$

= $\frac{10}{26}$

= $\frac{5}{13}$

5). cos(F) = $\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

= $\frac{EF}{DF}$

= $\frac{24}{26}$

= $\frac{12}{13}$

6). tan(F) = $\frac{\text{Adjacent side}}{\text{Adjacent side}}$

= $\frac{DE}{EF}$

= $\frac{10}{24}$

= $\frac{5}{12}$
