question 1

A
B
C
D

Answer 1

c) y = 7/5 x - 3

Explanation:

pass (0 , -3) (5 , 4)

y = mx + b

m = (y-y') / (x-x') = (4 - (-3)) / (5 - 0) = 7/5

b = y - mx = 4 - (7/5 x 5) = - 3

y = 7/5 x - 3

Answer 2

C

Explanation:

Y = mx + c is the general form where, m is the slope and c is the y- intercept.

Clearly, c is -3 (because the line cuts the y-axis at -3)

Looking at the line, we know the slope is positive; and

Using the two points (which are also the intercepts), it can be observed that change in y (which is 3) is greater than change in x (slightly more than 2, but less than 3).

change in y > change in x

change in y/change in x > 1

So, m > 1

The only option with slope > 1 is C
