slope=2/5,{10, 3} is on the line

Question

find the y-intercept: y= mx + b

___ = {---} ____ +b

Answer 1

You know the equation is

y = mx + b

So, plug in the data they gave you:

3 = 2/5 (10) + b
3 = 4+b
b = -1

So, the equation is

y = 2/5 x - 1

Since this is called the slope-intercept form of a line, take a stab at the y-intercept. (Hint: that is the point on the graph where x=0)
