Question

SO I HAVE A QUESTION IS THE EQUATION Y-Y1=M(X-X1) AND Y=MX+B SAME GIVE EXAMPLES PLSSSSSSSSSS

Answer 1

Both of these are ways to express linear equations.

$y - y_1 = m(x - x_1)$ is the equation for a line with slope m which contains the point $(x_1,y_1)$. This is called point-slope form.

$y = mx + b$ is the equation for a line with slope m and y-intercept b. That is, it contains the point (0, b). This is called slope-intercept form.

Both of these are perfectly valid ways of writing lines, though sometimes one will be easier to use than the other.

Answer 2

Answer:

Hey there!

Both of these can be used to write the equation of the line. However, for the Y-Y1=M(X-X1) equation, we must know one point on the line (X1, Y1) and the slope of the line, while in the Y=MX+B equation, we need to know the slope and the x or y intercept.

For example, we can convert from Y-Y1=M(X-X1) to Y=MX+B

For example, say the point is (2, 3) and the slope is 1

Then, we have Y-3=1(x-2)

This simplifies to Y-3=1x-2

And to Y=X+1

So it is very possible to change from one form to another.

Let me know if you need more help.
