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 <u><em>b</em></u> using <u><em>slope-intercept form*</em></u>, 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 <em>STANDARD FORM**</em>.

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: <em>y = mx + b</em>

**Standard form: <em>ax + by = c</em>
