Answer:
Step-by-step explanation: To find the slope we can use the equation (y2-y1/x2-x1). So we can use the points (2,7) and (3,9). The equation would look like (9-7/3-2). This solves to 2/1. This equation can be solved either way just make sure that you put the values in order like the reverse of this equation would be (7-9/2-3 which equals 2/1. Now that we have the slope we can use this to find the y-intercept. The formula is y=x + ?. For this instance we will use (2,7) for this so the equation will be 7= 2/1 * 2 + x. This solved equals 4 + 3= 7. With this we now know that y is equal to 3. So your slope formula will be 2/1x + 3 now with this we can solve for y when x = 8. 2/1(8) + 3 = 19. I hope this helps
Answer: (a) 9
<u>Step-by-step explanation:</u>
1st multiple of 3: 1(3x)
2nd multiple of 3: 2(3x)
3rd multiple of 3: 3(3x)
Sum = 4(1st multiple of 3) + 6
1(3x) + 2(3x) + 3(3x) = 4(3x) + 6
3x + 6x + 9x = 12x + 6
18x = 12x + 6
6x = 6
x = 1
Largest (3rd) multiple is: 3(3x)
= 9x
= 9 · 1
= 9
