Answer both and explain i help please :(

1.

2. B

Step-by-step explanation:

Hello There!

So for the first one they want us to find the slope intercept form of the line

y = mx + b

where m = slope and b = y intercept

to find the slope we do change in y divided by change in x

as y goes us 1 x goes up 3

so the slope (m) would be 1/3

the y intercept is at (0,4)

so the y intercept (b) is 4

now we put everything together and get that the equation in slope intercept form is

For the second one we need to do the same thing

for the slope: as y goes up 3 x goes down 4

so the slope would be -3/4

The y intercept is at (0.-1) so the y intercept is -1

now we put everything together and get that the equation is

or b

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
