Somebody please help me... its worth 10% of my grade and ill give you 40 points

1) y=-3/5+-3.5

For questions two and three, find the slope for the two points given and plug them into the slope-intercept form. You will also need to find the y-intercept (b).

Step-by-step explanation:

1) Point (2, -4), Slope = -3/5

  y = -3/5x+b

  -4 = -3/5(2)+b

  -4 = -1/2+b

  -3.5=b

y = -3/5+-3.5

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8
