Presuming this is y = 0.75x + 5
Turn it into a fraction
Y= 3/4x + 5
The +5 is your y intercept meaning where the line intercepts the y axis on a graph which in this case is (0,5)
The numerator/top number is your y coordinate so you’d go up 3
The denominator/bottom number is your x coordinate so you’d go right 4
