y-intercept of the equation

Question

"b" value (the y-intercept) for your equation that you find.  Given: (4,3) and m = -6.

Answer 1

Given: (4,3) and m = -6.

Slope-intercept form is y=mx+b.

Remember that "m" is the slope, and a point is written as (x,y) so in this equation x=4, y=3, and m=-6

Now plug your known values into an equation.

3=-6(4)+b

3=-24+b

3+24=b

27=b

Answer 2

equation of line in slope intercept form y = mx + b

substitute 4 for x; 3 for y and -6 for m and solve for b:

3 = -6(4) + b

27 = b
