Find the equation in standard form , of the line passing through points (2,-3) and (4,2)

Fudgin [204]

The form of linear equation that describes line is:

$y=sx+n$

First we must calculate the slope.

$s=\dfrac{\Delta{y}}{\Delta{x}}=\dfrac{2-(-3)}{4-2}=\dfrac{5}{2}$

Now it looks a bit more like this:

$y=\dfrac{5}{2}x+n$

All we need now is to put in y and x from one point doesn't matter which. I'll pick A.

The equation now looks like this:

$-3=\dfrac{5}{2}\cdot2+n$

Solve for n.

$-3=5+n \\n=-8$

And finally write the equation.

$f(x)=\dfrac{5}{2}x-8$

Hope this helps.

Bertha has $2400 more invested at 4% than she has at 5%. If her annual income from these two investments is $294, how much does

Oksana_A [137]

So
x (4%)
y (5%)
x=y+2400
0.04x+0.05y=294

Once you solve them, x=4600 and y=2200
so 4%= $4600
5%= $2200
