Find the slope and the y-intercept -8x-7y equals 21?
-8x-7y = 21
First let's separate the y and x and try to get the equation in the form of Y=mX+B (m is the slope and B is the y-intercept)
-8x-21=7y (we simply added 7y to both sides and subtracted 21 to both sides of the equation)
Now let's divide by 7 to both sides
-(8/7)-3=Y, so our slope is -(8/7) and our slope is -3
first of all, i dont see how slope and yintercept has anything to do with shopping. usually in an equation, y= mx+b, m stands for slope, and b is the y-intercept. x and y are just x and y. If the equation is mixed up, and is not in y=mx+b format, you need to solve to get y on one side, the slope, x, and whatever the presented constant is (which is the y-intercept) on…
What would the equation of a line be if it went through the point 2 comma 2 and its yintercept was 10?
We know that the line passes through points (2, 2) and (0, 10) (since the y-intercept is 10). Using these two points, we can find the slope of the line, m = (10 - 2)/(0 - 2) = 8/-2 = 4/-1 = -4. Now by using the slope, m = -4, and the y-intercept, 10, we can write the equation of the line in the slope-intercept form, y = mx + b which is y…
