Question

Find the equation of the line.​

Answer 1

Answer:

y=4x + 7

Step-by-step explanation:

Line=y=ax+b

b = where the line crosses the y-axis (where x=0). Here, it's 7.

a= vertical distance ÷ horizontal distance.

You can take any pair of distances to a point on the line, for example (4,1) is easy to read in the graph.

x=0 to 1 (horizontal distance=1-0=1)

and

y= 0 to 4 (vertical distance= 4-0=4)

a=4÷1=4.

So, the answer is y=4x + 7 as a= 4 and b=7.
