(7,5)(-4,-1)
slope = (-1-5) / (-4-7) = -6/-11 = 6/11
y - y1 = m(x - x1)
slope(m) = 6/11
(-4,-1)...x1 = -4 and y1 = -1
now we sub...pay close attention to ur signs
y - (-1) = 6/11(x - (-4) ...not done yet...
y + 1 = 6/11(x + 4) <===
So because it's x^2 that means it's a parabola. The 3 before it is it's stretch factor (slope, so instead of going over one up one it goes over one up 3)
Answer:
9(y-5)/10(y-1)
Step-by-step explanation:
If brainiest is earned its greatly Appreciated
<span>xcos(y) --> For this part, use the product rule, which would mean
cosy - xsiny * dy/dx
sinx's derivative is just cosx, so we get as a final answer
cosy - xsiny * dy/dx - cosx =0
-xsiny *dy/dx = cosx - cosy
dy/dx = cosx - cosy / -xsiny
When y=0,
dy/dx = cosx - cosy / -xsiny
dy/dx = cosx - cos(0) / -xsin(0) [note: sin(0) =0]
dy/dx = undefined [since you can't divide by 0]</span><span>
