No idea need some help please...if you can explain thats great too. THANKS!?

One particularly large ant hill found in 1997 measured 40 inches wide at the base and 18 inches high. Whar was the slope of the ant hill?





For banquets, Flourishing Flowers charges $60 for each standard floral arrangement plus a one time $125 fee for delivery and set up , Write an equation in a slope-intercept form that shows the cost y for flowers for x number of arrangements.





Find an equation in thr slope-intercept form for the line:


slope= 4 , y-intercept = 4





Find an equation in slope - intercept form for the line passing through each pair of points: ( -4, 4) , ( -5, -3)





Find an equation in slope-intercept form for the line passung through each pait of points: (4, 7) , ( 1, 4 )

#3. Y=4X + 4


#4. -3-4/-5-(-4); so -7/-1 so 7 is you slope, then slope intercept form is (y-y1)=M(x-x1), choose and pair of points, you should get the same answer no matter which you use, so


y-(-4) = 7(x-4)


y + 4 =7x - 28


y = 7x -32





#5 is the same way find your slope first y2-y1/x2-x1


4-7/1-4 = -3/-3 so m=1


y-1 = 1(x-4)


y -1 =x -4


y=x -3

This sounds like they are wanting you to use Pythagoreans theorem here. So you would do 40 squared + 18 squared = x and then find the square root of x

y=125+60x If I remember correctly slope-intercept form is y=mx+b, so that form should be correct.

4=4x+b???
