Answer:
y = 2x -5
Explanation:
The first point tells the y-intercept of the line, -5, the value of y when x=0.
The slope is ...
(change in y)/(change in x) = (3 -(-5))/(4 -0) = 8/4 = 2
The slope-intercept form of the equation of a line is ...
y = (slope)x + (y-intercept)
Filling in slope=2 and y-intercept = -5, the equation is ...
y = 2x -5
