(0,1) (3,-8) linear equation

Dmitry [639]

Answer:

The answer is

$y = - 3x + 1$

Step-by-step explanation:

❃Incase you forgot what the linear equation formula is ☟

$y = mx + b$

❃Incase you also forgot, The is what the slope formula is ☟

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

➊ First: We are going to be solving for the slope.

$m = \frac{ - 8 - 1}{3 - 0} = \frac{ - 9}{ \: \: \: 3} = - 3$

➋Second: We find the y-intercept.

$y = mx + b \\ - 8 = - 3(3) + b \\ - 8 = - 9 + b \\ \frac{ + 9 = + 9 \: \: \: \: \: }{1 = b}$

➌Third: Plug in.

$y = - 3x + 1$

$\textbf {Let's Solve :}$

<h3>Question 1 :</h3>

$\textsf{4x - 3 = 2x +7}$

$\textsf{4x -2x = 3 +7}$

$\textsf{2x = 10}$

$\textsf{x=5}$

<h3>Question 2 :</h3>

$\sf{2x + 6 = 7 \times 14}$

$\sf{2x + 6 = 98}$

$\sf{2x = 98-6}$

$\sf{2x = 92}$
