slope intercept form
y=mx+b
where m is the slope and b is the y intercept
if we change from point slope form
y-y1 = m(x-x1)
we distribute
y-y1 = mx -x*x1
then add y1 to each side
y = mx -x*x1+y1
remember x and y are variables and should stay in the equation
m,x1,y1 are numbers from the problem
you may have to calculate the slope (m) from the formula
m = (y2-y1)/(x2-x1) from two points on the line
Hello!
Explanation: The y-intercept is the point on a graph at which the graph crosses the y-axis.
Slope-Intercept Form: y=mx+b
Let m represent the slope.
(0¹,b¹) (x²,y²)
m=rise/run=y-b/x-0
x(m)=y-b/x)x
mx=y-b
+b +b
mx+b=y
And switch sides of an equation.
y=mx+b
Hope this helps!
