Write the equation of a line with the given condition 1) m=4, y int is -2 y=4x-2 2) m=2/3 x intercept 6 3) m= -2/3 contains point (2,4) 4) contains (1,2) (3,7) 2) y=mx+b y=2/3x+b find b (6,0) on line Sub x=6 y=0 into equation 0=2/3(6)+b 0=4+b -4=b solution = y=2/3x-4 3) y=mx+b y=-2/3x+b find b (2,4) 4= -2/3(2)+b 4= -4/3+b 16/3=b solution = y= -2/3x+16/3 Equation for a slope intercept form *solve for y m= slope b = y intercept y=mx+b We can graph the line using pt (0,6) and m *No table value *Lines with equal slopes are parallel ? ?
