Option a is more steeper
The slope intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept form formula is used to find the equation of a line when given the slope of the straight line and the y-intercept( the y-coordinate of the point where the line intersects the y-axis).
According to the slope intercept form of equation
y = mx + c
where m = slope of the line
c = y-intercept
the steeping of the graph is determined by the slope of the line on the graph. The more is the value of the slope the more steeper the graph will be of the given line.
In option a: m=3 whereas option b: m=1/2
So y=3x+7 is more steeper
