$m(3-4m)=7+4(8-m^2) \\
3m-4m^2=7+32-4m^2 \\
3m-4m^2+4m^2=7+32 \\
3m=39 \\
m=\frac{39}{3} \\
m=13$

Suppose the equation of a line is 2x − 4y = − 8. Which coordinate pair represents the y-intercept?

Ira Lisetskai [31]

Answer:

(0,2)

Step-by-step explanation:

Convert the equation to <em>y=mx+b</em>.

You get y=1/2+2.

Since x is always 0 in your y-intercept and the y value is equal to <em>b, </em>you get (0,2) as your coordinate pair.

Please help!! Asap!!

We notice that for x = 2 , or x = 4, the value of y=0 (x intercept),

replace x by any of the latter value in y=a(x-3)² -1

===> 0= a( 2-1)² - 1====>a=1

What is the equation of the line shown in the graph drag & drop the expressions ro write the equation of the line in slope i

vredina [299]

Answer:

y = 2(x + 3) + (-2) is the required equation.

Step-by-step explanation:

Here the given points are A( -1,2) and B(-3-2)

Now, slope of the equation = $\frac{y_2 - y_1}{x_2 - x_1} = \frac{-2 -2}{-3-(-1)} = \frac{-4}{-2} = 2$

Hence, the slope of the equation is m = 2

Now, by POINT SLOPE FORMULA:

The equation of a line with slope m and point (x0, y0) is given as

(y - y0) = m (x -x0)

So, here the equation of line with (-3, -2) is

y - (-2) = 2 (x - (-3))

or, y + 2 = 2(x + 3)

⇒ y = 2(x + 3) + (-2) is the required equation.
