Write the equation of a line in slope-intercept form, y = mx + b, between the following

kupik [55]

Answer:

$y = \frac{3}{2} x + 2$

Step-by-step explanation:

In the slope-intercept form y= mx +b, m is the slope and b is the y- intercept.

$\boxed{slope = \frac{y1 - y2}{x1 - x2} }$

Using the formula above,

$slope = \frac{5 - ( - 4)}{2 - ( - 4)}$

$m = \frac{5 + 4}{2 + 4}$

$m = \frac{9}{6}$

$m = \frac{3}{2}$

Substitute the value of m into the equation:

$y = \frac{3}{2} x + b$

To find the value of b, substitute a pair of coordinates into the equation.

When x= 2, y= 5,

$5 = \frac{3}{2} (2) + b$

5= 3 +b

b= 5 -3

b= 2

Thus, the equation of the line is $y = \frac{3}{2} x + 2$ .

Write an equation in standard form of the line that passes through the given point and the given slope. (-9, -4); m = -1/3

tigry1 [53]

<h2>Answer:</h2>

First, we must determine b using slope-intercept form*, the given point, and the given slope.

$-4 = -\frac{1}{3}(-9) + b\\\\-4 = -3 + b\\\\-1 = b$

Second, we need to set up the equation of the line in slope-intercept form.

$y = -\frac{1}{3}x - 1$

Third, we convert the above equation to STANDARD FORM**.

$y = -\frac{1}{3}x - 1\\\\\frac{1}{3}x + y = -1$

We now have our equation: $\frac{1}{3}x - y = -1$

*Slope-intercept form: y = mx + b

**Standard form: ax + by = c
