Hi, i would like to know if you can answer this question for me
Find the x and y intercept fo y = 8x - 5
thanks
The y-intercept is the y-cordinate of the point where the graph crosses the y-axis. For example in the diagram below the red dot marks the place where the graph crosses the y-axis.
Since this point is on the y-axis its coordinates ate (0,b) for som number b. This point is on the line
y = 8x - 5
Thus
b = 8
0 - 5 = -5
Thus b = -5. Hence the y-intercept is -5.
Can you now find the x-intercept?
