Write an equation in slope-intercept form from the points (0, 3) and (-4,-1)
Bezzdna [24]

Answer:

y = x + 3

Step-by-step explanation:

Slope-intercept form is represented by the formula y = mx + b. We can write an equation in point-slope form first, then convert it to that form.

1) First, find the slope of the line. Use the slope formula  m = \frac{y_2-y_1}{x_2-x_1} and substitute the x and y values of the given points into it. Then, simplify to find the slope, or m:

m = \frac{(-1)-(3)}{(-4)-(0)} \\m = \frac{-1-3}{-4-0} \\m = \frac{-4}{-4} \\m = 1

Thus, the slope of the line must be 1.

2) Now, since we know a point the line intersects and its slope, use the point-slope formula y-y_1=m(x-x_1) and substitute values for m, x_1, and y_1. From there, we can convert the equation into slope-intercept form.

Since m represents the slope, substitute 1 in its place. Since x_1 and y_1 represent the x and y values of a point the line intersects, choose any one of the given points (either one is fine) and substitute its x and y values into the equation, too. (I chose (0,3).) Finally, isolate y to find the answer:

y-3=1(x-0)\\y-3 = x\\y = x + 3

Having some trouble with this...pls help (in fraction form)
Yuri [45]

Answer:

\frac{17}{6} or 2\frac{5}{6}

Step-by-step explanation:

1.Find the Least Common Denominator (LCD)

 LCD = 6

2.Make the denominators the same as the LCD.

   2+\frac{1*3}{2*3}  + \frac{1*2}{3*2}

3.Simplify. Denominators are now the same

   2+\frac{3}{6} + \frac{2}{6}

4. Join the denominators

   2+\frac{3+2}{6}

5.Simplify

   2\frac{5}{6} = \frac{17}{6}

First do the solving you CAN do

17(x+5)=4.67

then, get x by itself my moving 5 and 17 over

(17(x+5)/17=4.67/17

x+5=.<span>2745

x=-</span><span>4.725

and there's the answer!</span>
