Write an equation in point slope form that passes through (-14, - 6) and the slope is 2/3

s344n2d4d5 [400]

Answer:

y=2/3x - 6

Step-by-step explanation:

use the formula y=mx+b. the m of this equation is equal to the slope and you know that the slope is 2/3. the b of the equation is equal to the y-intercept so, to find b you simply look at the points given. the points are written in (x,y) form so if -14 is x, -6 must be y. remember to KEEP CHANGE CHANGE your signs so that plus sign becomes negative 6. Hope this helps!

Someone help please - area of circles!

Reika [66]

R=d/2
R=40/2
R=20
A=πr^2
A=π20^2
A=π400
A=1256.637061
Area of triangle=(b*h) /2
A=(40*20)/2
A=800/2
A=400
Area of circle-area of triangle=area of shaded region
1256.637061-400=856.637061
Hope this helps!
