Question

Exercise 21.2

1. For each graph with the given intercept and passing through the given poi
write down the equation of the corresponding function.
(i) Intercept = 1 and (3, 10)
(ii) Intercept = 2 and (3, 3)
(iii) Intercept = 5 and (2, 1)
(iv) Intercept = 0 and (3, 12)
(v) Intercept = - 4 and (3,8)
(vi) Intercept = -5 and (-2, -9)

Answer 1

1.y=3x+1

2.y=1/3x+2

3.y=-2x+5

4.y=4x

5.y=4x-4

6.y=-2x-5

Explanation:

(i)

y=mx+c

10=(m)3+1

10=3m+1

10-1=3m

m =3

y=3x+1

And so on...
