y=5x+12 isn't the answer

Answer 6

do any of you know how to help me with these ? i don't understand -

B. (4, 21)
C. (4, 18)
D. (3, -3)
E. (-2, 13)
F. (-1, 9)

Answer 7

Ok, so 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

Answer 8

\[(x_1, y_1) \implies (-1,3)\] since we are given all this information we can go directly to using point - slope form: \[y-y _{1}=m(x-x _{1})\] we leave y and x alone, and plug in points (x1,y1) as presented above. So we have the following \[y-(-1) = m(x-3)\] 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 \[y+1 = 5x-15 \implies y=5x-16\]
