So if an equation with two variables, you need to also two equations to solve the values of the variables. but if you knew the value of the one variable then onl one equation is need. for example an equation x + y = 20
where x = 5
then to solve the value of y, substitute the value of the equation
5 + y = 20
then transpose 5 to the other side
y = 20 - 5
y = 15

The slope is 3/4
Step-by-step explanation:
You can Y2-Y1/X2-X1 to find the answer to this question
Since the points are (-2,3) and (2,6) it will be..
6-3/2+2 ** the 2 becomes a plus in the denominator because negative and negative is positive
3/4 is the slope
