Which point on the grid have they not explored? Which point on the grid have they not explored? A. (0, 3) B. (-2, -2) C. (3, -3) D. (-3, 1)

(3,-3)

Step-by-step explanation:

See attachment 1 for complete question

The unexplored point

To properly understand my solution, I will make use of another attachment where each of the given points will be identified on the point grid [See attachment 2]

From the second attachment, all points in the shaded region have been explored.

Only (3,-3) has not been explored

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form

i believe the answers 600m
