If two points on line l above have coordinates (0, a) and (2, −3), and the slope of the line is a, then what is the value of a?

ANSWER:

If two points on line l above have coordinates (0, A) and (2, −3), then the value of A is -1

SOLUTION:

Given, two points on line l have coordinates (0, A) and (2, −3),

And the slope of the line is A,

We need to find a value.

We know that, slope of a line on which (x1, y1) and (x2, y2) are two points is given by

Here,in our problem,

now, substitute the values in formula we get

2A = -3 –A

2A+ A = -3

3A = -3

A = -1

Hence, the value of A is -1.

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
