Question

How do i get the right answer

Answer 1

Equation for these two coordinates: y=-4x-15

Explanation:

If you can, try using desmos and use the 'y='.

I got y=-4x by observing if the line is symmetrical to the dots.

The line was above, so I subtracted a number like 12, 13, 14, and 15.

This is how I got y=-4x-15.

If the dots are positive to each other climbing up like this /, use a positive number. If it is the opposite, use a negative number.

(I hope this helps.)

Answer 2

Answer: y=-4x-15

Explanation:

HACKS MODE ON

I'm assuming that these are 2 points on a line

The slope is (y2-y1)/(x2-x1) so (-19-(-7))/(1-(-2)) so (-19+7)/(1+2)=-12/3 or -4.

Now, we add 4 to -19 to get -15

So: the graph is y=-4x-15
