Answer:

y = 2x - 1

Explanation:

The equation of a line is typically in the form of: y = mx + b, where m = slope and b = y-intercept. In the given graph, you have two points: (4, 7) and (2, 3). First you can find slope using the slope formula:


((y_(2)-y_(1)))/((x_(2)-x_(1)))=((7-3))/((4-2))=(4)/(2)=2

Since slope = 2, we just need to find 'b' in order to finish our equation. We can use the point (4, 7) for the values of 'x' and 'y' to solve for 'b':

y = mx + b or 7 = (2)(4) + b

7 = 8 + b or b = -1

y = 2x - 1
