We know that To calculate the slope we need to take two points from data in a table

point 1 (x1,y1) and point 2(x2,y2)

The formula to calculate the slope between two points is equal to

substitute the values and solve for

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
