Question

Can someone please help me with math

Answer 1

Explanation:

A line can be expressed as

y=mx+b, where m is the slope and b is the y intercept (the value of y when x=0)

Any two points form a line when connected.

m=(y2-y1)/(x2-x1), in this case we have points (0,4) and (5,2) so

m=(2-4)/(5-0)

m=-2/5 so our line is now

y=-2x/5+b, using (5,2) we can solve for b

2=-2(5)/5+b

2=-2+b

b=4, so the line is

y=-2x/5+4

Answer B

Answer 2

B

Explanation:

Hey There!

they are asking for the equation in slope intercept form

Slope intercept form is y=mx+b

where m equals slope and b equals y intercept

to find the slope we do change in y over chang in x

as y goes up 2 x goes down 5 so the slope would be -2/5

the y intercept is at (0,4) so the y intercept is 4

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

y=-2/5x+4

so we can conclude that the answer is B
