Mandarinka [93]

Answer: $y=8x-25$

Step-by-step explanation:

Given

Line passes through $(3,-1)\ \text{ and}\ (4,7)$

Equation of line when it passes through two points $(x_1,y_1),(x_2,y_2)$

$\Rightarrow \dfrac{y_2-y_1}{x_2-x_1}=\dfrac{y-y_1}{x-x_1}$

Insert the values

$\Rightarrow \dfrac{7+1}{4-3}=\dfrac{y+1}{x-3}\\\\\Rightarrow \dfrac{8}{1}=\dfrac{y+1}{x-3}\\\\\Rightarrow 8x-24=y+1\\\Rightarrow y=8x-25$

What is the slope of the line that passes through the point (9,4) and (3,9)?

Fantom [35]

Step-by-step explanation:

m is for slope of the line that passes through

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{9 - 4}{3 - 9}$

$m = \frac{5}{ - 6} = - \frac{5}{6}$
