1) Slope: (4-5)/(3-4)=1 Make a point slope equation: y=(x-4)+5 X-Intercept: -1 Plug 0 in for y and solve Y-Intercept: 1 Plug 0 in for x and solve
2) Slope: (3-3)/(2-2)=Does Not Exist You can't find any of these with only one point given
3) Slope: (4-1)/(5-3)=1.5 Write an equation in point slope form: y=1.5(x-3)+1 X-Intercept: 7/3 Plug in 0 for y and solve Y-Intercept: -3.5 Plug in 0 for x and solve
4) Slope: (2-5)/(4-2)=-1.5 Write an equation in point slope form: y=-1.5(x-2)+5 X-Intercept: 16/3 Plug in 0 for y and solve Y-Intercept: 8 Plug in 0 for x and solve
