SLOPE OR GRADIENT 1


Find the slope of a line 7x – 8y + 10 =0.

Solution

7x – 8y + 10 =0

We strive to re-write it in the form y=mx+c.

– 8y + 10 = -7x    [shifting 7x to the right side.]

– 8y = -7x – 10    [shifting 10 to the right side.]

– 8y = -7x10    [dividing by -8 all over]
 -8      -8      -8

y = 7x/8 + 5/4 which is like y=mx + c

Hence Slope is 7/8 


TRY THIS……………………….



Find the slope of a line 9x – 4y + 14 =0.
