2.2 Linear equations are one variable 2x-3=0 is a linear equation in one variable Linear equation with two variables 2y+2x=0 Such an equation represents a line How do we find equation for a line Given two points (1,8) (0,1) on a line. Find an equation. Y-y1=m(x-x1) to change to slope intercept distribute slope and add y sub one value to equation. How can you tell the relationship between two lines The two lines can be parallel or perpendicular. Set equations equal to one another. Y=1/2x-1 Y=x+1 To find x then substitute x value into original equation. 2.4 Complex Numbers I=sqrt of -1 2=2+0i
