y = mx + b   ;   m = slope
y = 6x + b
Now use the coordinates (0,4), 0 for x, 4 for y to solve for b (constant)
 
4 = 6(0) + b
 
4 = 0 + b
b = 4
 
y = 6x + 4
Hi Eugenia;
The slope-intercept form equation is...
y=mx+b
m=slope
b=y-intercept, the value of y when x=0
The information provided is that the slope is 6.
The y-intercept, value of b, is 4.
y=6x+4
