Answer:-
Find the equation of line passing through the points(-1,7)and (0,15)
Answer:-
Step 1:- finding the slope of line = m y2-y1 15-7 8 Formula to find slope ------- = ------- = ------ = 8 x2-x1 0-(-1) 0+1 so ,slope of a line is 8 step 2:- The point slope form of equation (y-y1)=m(x-x1) We know that (x1,y1) is (-1,7) and m=8 So (y-7)=m-(x-(-1)) (y-7)=8(x+1) y-7=8x+8 +7 +7 --------- y=8x+15 step 3:- The equation of the line becomes y=8x+15 For more help on this,you can reply me.
