SOLUTION: The x intercept coordinate is (4,0) the y intercept coordinate is (0,3). When the x coordinate is -4, what is the y coordinate? When the y coordinate is -3, what is the x coordinat

Question 664254: The x intercept coordinate is (4,0) the y intercept coordinate is (0,3). When the x coordinate is -4, what is the y coordinate? When the y coordinate is -3, what is the x coordinate?
Answer by ReadingBoosters(3246) (Show Source): You can put this solution on YOUR website!
slope is (0-4)/(3-0) = -4/3
y intercept is 3
y = -4/3x + 3
...
Solving for y when given x
y = -4/3(-4) + 3
16/3+3
16/3 + 9/3
25/3 = 8.333 = y
(-4, 8.3)
...
Solving for x when given y
-3=-4/3x+3
-4/3x = -6
x = -6(-3/4)
18/4 = 4.5 = x
(4.5, -3)
...
