Best ResponseYou've already chosen the best response.0do any of you know how to help me with these ? i don't understand  Which point lies on the line described by the equation below? y  3 = 2(x + 5) A. (3, 17) B. (4, 21) C. (4, 18) D. (3, 3) E. (2, 13) F. (1, 9)

Best ResponseYou've already chosen the best response.1Ok, so dw:1434945650832:dw so we want it in the equation of a line form (y=mx+b) to do this we can do the following: We are given a point (x,y) which we will treat as

Best ResponseYou've already chosen the best response.1\[(x_1, y_1) \implies (1,3)\] since we are given all this information we can go directly to using point  slope form: \[yy _{1}=m(xx _{1})\] we leave y and x alone, and plug in points (x1,y1) as presented above. So we have the following \[y(1) = m(x3)\] now we know that our slope is 5 so we plug that in for m since m represents the slope in y = mx+b form, and b is the y  intercept. Doing some algebra with the above equation we get \[y+1 = 5x15 \implies y=5x16\]

Best ResponseYou've already chosen the best response.1For your second question, set your equation up in y = mx+b form and graph it out and see if the coordinates are on the line (this will help you visualize it).
