Answer:20= 3x + 23
Step-by-step explanation:
Y and X are the two variables in the graph m is the gradient (dy/dx) and b being the intercept
Hello,
Slope is rise/run, or y/x, and if you are given two pairs of points, this is the equation needed: (y2-y1) over (x2-x1).
Let me plug in the numbers: (4-(-2) over 5-(-3). And that is 6/8, which then is simplified to 3/4. So the slope of those two given points is 3/4. We do not divide or simplify it into a decimal because slope is a fraction, so we leave 3/4 as it is.
Hope this helps, and that my explanation is not too confusing!

C because x represent the cost of books while 2 can be an additional price for the pens
The girl's speed is 1380mm/sec * 1cm/10mm * 60sec/minute (since 1cm=10mm and 60 sec=1 minute)= 1380*60cm/10min= 1380*6cm/min
=8280 cm/min. For the turtle, we have 1584 m/hr * 1 hr / 60 min * 100 cm /1m (we have to make sure that they cross out, so e.g. for the hour we multiply it by 1 hr/60 min since the original hour is on the bottom)= 158,400cm/60min
=15840cm/6min
= 2640 cm/min
Since the girl is 8280 cm/min and the turtle is 2640 cm/min, we divide them to get 8280/2640= around 3.136 cm/min
