Question

Find the points at which the graph of the equation - 4y = 15 - 5x crosses the x - axis and the y-axis.

15 – 5x crosses the x = axis and the y = axis.
A. (3,0) and (0, -3.75)
B. (0,3) and (0, -3.75)
C. (-3.75, 0) and (0,3)
D. (3,0) and (-3.75

Answer 1

Answer: A (3,0) and (0, -3.75)

Explanation: To find Y intercept let X equal 0, then solve for Y

-4y=15-5(0)

5(0) cancels out so -4 times what equals 15? Divide 15 by -4=-3.75, that is your Y intercept. (0,-3.75)

To find X intercept let Y equal 0, then solve for X

-4(0)= 15-5x

-4(0) cancels out so 5 times what equals 15? 3. That is your X intercept

(3,0)
