The correct option is (d).

d) (2,-6) & (4,-16)

Now, To find the correct option that is equivalent to this equation, we can begin by narrowing down the given options.

Since, The slope contains a negative number, that's mean the second point must have a lower y value than the first x value.

Hence, By using this criteria, we can eliminate the first and the third option.

Now, we can check the second and fourth option as;

We can test using by putting in values.

Let's plug in the point values to check whether they work:

Hence, For option 2:

y = -5x + 4

-24 = -5(4) + 4

-24 = -20 + 4

-24 ≠ -16

And, For option 4:

y = -5x + 4

-16 = -5(4) + 4

-16 = -20 + 4

-16 = -16

Therefore, The correct option is option (d).

The complete question is this;

Which line has an equation of y= -5x+4 in slope intercept form?

A line passing through the points -

a) (1,9) & (3,19)

b) (2,-14) & (4,-24)

c) (1,1) & (3,11)

d) (2,-6) & (4,-16)
