y = 2x-5

Step-by-step explanation:

Let's take two points from the line.

(3,1) and (4,3)

Now,

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

m = 2/1

so, m = 2

Now,

y = mx + b

or, 1 = 2×3 + b

or, 1 = 6 + b

so, b = -5

Now,

y = mx + b

now,

y = 2x-5

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1
