Write the equation of the line that passes<br> through the points (3, 1) and (-2, 6).
tia_tia [17]

Answer:

Equation is Y=mx+c (that's how I know it, it may differ)

Step-by-step explanation:

First get the slope which is M and you just gotta do the second y - the first y from the brackets and divide them by the second x - the first x

6-1 /-2-3 = 5/-5

= -1

So now u gotta find c, C= Y-mx

And u have got two brackets, which have an x and y, and u now have m.

Pick one of the brackets like (-2,6) and put them in the equation so it will be : C =6+1*-2

So C =4

The equation now is : Y = - 1x + 4
