Answer:
Option 4
y = 2x + 3
Explanation:
Equation of a line in slope intercept form is
y = mx + b
where m = slope and b = y-intercept
Slope m = rise/run = Δy/Δx with Δy = change in y values between any two points on the line and Δx = corresponding change in x values
b is the y-intercept, value of y when x = 0 and indicates the point at which the line crosses the y-axis
Let's take two distinguishable integer points on the line
(0, 3) and (1, 5) are two points
rise = Δy = 5 - 3 = 2
run = Δx = 1 - 0 = 1
So slope = 2/1 = 2
Since y = 3 at x = 0, y-intercept b = 3
Equation of line is
y = 2x + 3
