the slope is the m. so look and see what the slope is......
the b is the y coordinate in the point given. see if that helps you without giving the answer away!!!!!

In this case, m is the slope, which is -4. If you substitute -4 for m, you get y=-4x+b. Plug in the numbers -7 for x and -5 for y and solve for b. Now you have both the values for m and b.

Substitute the x and y into the equation to find the y-intercept (b).
-5=(-4)(-7)+b
-5=28+b
-33=b
m is given as -4 and you solve for the y-intercept b, which is -33.

the parts of a slope are rise and run
rise is the dots going up, run is the dots going sideways
m is the slope and b is the y intercept
if the slope is only one number, you put the number over one
if the rise is negative go down
if the run is negative go left

Rise and Run I think

(m) is the slope and (b) is the y-intercept.
