Question 946225: I HAVE the gradient of a line
x = 0.5
from this how do i find the y intercept please??
i know that the equation is y=0.5x +3.5
but i got the answer from drawing a graph but i need to get to this answer without the graph how is this possible

You can put this solution on YOUR website!
The equation you have is in slope-intercept form, y=mx%2Bb where m is the slope and b is the intercept.
So in your case,
m=0.5
b=3.5
