Help pls number 17 show work if needed!ty!

Step-by-step explanation:

Use the coordinates of two points to determine the slope of the line through them.

Using (3,105) and (1,35):  slope = (105-35)/(3-1) = 35

Point-slope equation for line of slope 35 passing through (1,35):

y-35 = 35(x-1)

y = 35x, which is equivalent to Brian's equation.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

6e14 is the answer.
