Question

У=2х+1 и у =-3х+6..................

Answer 1

Ответ:

у = 3х + 6,

у = -2х - 1,

3х + 6 = -2х - 1,

3х + 2х = -1 - 6,

5х = -7,

х = -1,4,

у = 3*(-1,4) + 6 = -4,2 + 6 = 1,8,

или:

у = -2*(-1,4) - 1 = 2,8 - 1 = 1,8,

Answer 2

It appears you're providing two equations in the form of "y = mx + b", where "y" is the dependent variable, "x" is the independent variable, "m" is the slope, and "b" is the y-intercept. The equations you've given are:

1. $y = 2x + 1$
2. $y = -3x + 6$

If you're looking to solve for the point of intersection (where the two lines represented by these equations intersect), you can set the two equations equal to each other:

$2x + 1 = -3x + 6$

Now, we can solve for $x$:

$2x + 3x = 6 - 1$

$5x = 5$

$x = 1$

Now that we have $x = 1$, we can substitute this value into either of the original equations to find the corresponding $y$ value. Let's use the first equation, $y = 2x + 1$:

$y = 2(1) + 1$

$y = 2 + 1$

$y = 3$

So, the point of intersection is $x = 1, y = 3$.
