PLEASE, HELP ME IN THIS!!

y = x+40

Step-by-step explanation:

First, calculate the rate of the rate by using the slope formula, .

m = (50-47)/(10-7) = 3/3 = 1

Now plug m = 1 into the slope-intercept form, y = mx+b. Also plugin y = 42 and x = 2 in other to find the y-intercept (b).

42 = 1(2)+b

42-2 = b

b = 40

Replace b with 40 in the slope-intercept formula.

y = x+40

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
