Given the points (2 , 1.5 ) and ( 0 , 4.5 )
the slope of the line will be calculated as following :
So, the slope = -1.5
To write the equation of the line in slope intercept form
the form will be y = mx + b
where m is the slope and b is the y-intercept
y-intercept is the value of y at which x = 0
which is the point ( 0 , 4.5)
so, b = 4.5
so, the equation of the line will be:
y = -1.5 x + 4.5
