Question 23374: please solve y=4*2+4. i have to write an equation is slope intercept form and the two points on my line are (2,4) and (3,8). the slope is 4. please write the equation in slope intercept and slove it! i need this like asap!!!! thank you ssoo much!!

If you know that the slope is 4 , and it passes through the point (2,4), then your first step is to use y=mx+b to find b which is the y-intercept. Substitute everything you know (m=4, x= 2 and y = 4) into that formula:

y=mx+b
4 = 4*2 + b
4=8 +b
b=-4

So graph the line by starting at the y-intercept going DOWN 4 units on the y-axis. Put a point there. Then with your pencil on that point, rise UP 4, and go RIGHT 1, and put another point. Connect the points, and that should give you a line that goes through the points you mentioned in the problem. The equation of the line is , and the graph should look like this:
