What is point-slope?
Show answer
y−y1=m(x−x1)y - y_1 = m(x - x_1).
What is q1?
Show answer
Find the slope between (−2,4)(-2, 4) and (2,−4)(2, -4). [1 point]
What is q2?
Show answer
What slope is parallel to y=−3x+7y = -3x + 7? [1 point]
What is sign errors in point-slope?
Show answer
y−y1=m(x−x1)y - y_1 = m(x - x_1): subtracting a negative coordinate becomes addition, e.g. y−(−3)=y+3y - (-3) = y + 3.
