Question

Can someone do the whole thing

Answer 1

1

Explanation:

y=mx+b, equation for slope-intercept line

we can work out the equation based on given two points (1,1) and (7,4)

• m=(y2-y1)/(x2-x1)= (4-1)/(7-1)= 3/6= 1/2

y=1/2x+b

For (1,1)

• 1= 1/2+b ⇒ b= 1/2

For (7,4)

• 4=7*1/2+b ⇒ b= 1/2

So we get

• y= 1/2x+1/2

The answer is 1 for question mark
