Graph the equation y=kx+1 if it is known that the point M belongs to it: M(2, -7)

Question

Please help! I don't understand!

Answer 1

plug M into the line

-7 = k(2) + 1

2k = -7 -1 = -3

k = -8/2 = -4

y=(-4)x + 1

the line has a y intercept of 1 and slope = -4. The line is downward sloping.

plot (0, 1) and (2,-7) and draw a straight line through them.
