Write a rule for the linear function in the graph

(3,-1)(4,3)
slope(m) = (3 - (-1) / (4 - 3) = 4/1 = 4

y = mx + b
slope(m) = 4
use either of ur sets of points(4,3)...x = 4 and y = 3
now sub and find b, the y int
3 = 4(4) + b
3 = 16 + b
3 - 16 = b
-13 = b

so ur equation is : y= 4x - 13 <==

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
