Question

What is the equation for a line that passes through the points (-5,-4) and (10,23)?

Answer 1

So you use the point slope stuff.

y-y=m(x-x)

To find the slope, subtract two y values over two x values that are also sibtracted in the same order.

IN this case, you could do (-4 - 23)/-5 - 10

Which is 9/5

So now you plug in the x and y values (doesnt matter which point)

y+4=9/5(x+5)

Make it slope intercept form

y=9/5x-13
