a line of gradient 3 passing through a(-1,6) meet the x axis at b. another line through a meets the x axis at c(2,0). (i)find the equation of AB and AC (ii)Calculate the area of triangle ABC

The figure shows triangle def and line segment bc, which is parallel to ef: triangle def has a point b on side de and point c on side df. the line bc is parallel to the line ef. part a: is triangle def similar to triangle dbc? explain using what you know about triangle similarity. part b: which line segment on triangle dbc corresponds to line segment ef? explain your answer. part c: which angle on triangle dbc corresponds to angle f? explain your answer. asap
