21. 1/7 3/8 1/2
23. 3 5/8 3 3/8 3 1/2
25. 1/6 3/4 2/3
First set the equation equal to y by adding x to each side, then divide everything by 8. then set x to zero and solve to find the y - intercept of 1/2 which is just 4/8 reduced. you get this answer because x/8 becoming 0/8 is just 0 leaving you with only 1/2. then reset the equation with x and set y to zero and solve for x to get the x- intercept of -4. you get this by subtracting 1/2 from both sides leaving you -1/2=x/8 and multiply by 8 to get -4=x
Answer:
(1/2, 0)
Step-by-step explanation:
To find the y-intercept, set x = 0 and find y: y = 4(0) - 2 = -2, so that we have the point (0, -2).
To find the x-intercept, set y = 0 and find x: 0 = 4x - 2, or x = 1/2, so that we have the point (1/2, 0). This corresponds to the first answer choice.
