Question 47561
Looking at the Line L, the slope is ______ and the value of y when x=4 is____
The points on my sample graph for Line L are (-1,0) (0,2). Knowing this, I found the slope to be 2 but I don't get how to find the value of y when they give you what x is.
DO YOU WANT ANALYTICAL OR GRAPHICAL METHOD?IT LOOKS YOU WANT TO READ FROM GRAPH.IF SO GO TO X=4 POINT..THAT IS ON THE X AXIS GO TO A POINT P AT 4 UNITS FROM ORIGIN.FROM P DRAW A PERPENDICULAR TO X AXIS OR PARALLEL TO Y AXIS.LET IT MEET THE LINE L AT Q.MEASURE LENGTH OF PQ ..THAT IS THE VALUE OF Y WHEN X=4.YOU SHOUD GET Y=10..
