y=x+4

Step-by-step explanation:

y=mx+c,

where m is the gradient and c is the y-intercept.

Using the above formula,

y=1x+c

since 1x is redundant, we simply write it as y=x+c.

To find the y-intercept, substitute a coordinate into the equation.

When x=3, y=7,

7= 3+c

c= 7-3 (-3 on both sides)

c= 4 (simplify)

Thus the equation of line AB is y= x+4.

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 !
