Answer:
y = -4x + 15
Step-by-step explanation:
slope = (-1 -7)/(4-2) = -8/2 = -4
y = mx + b
7 = -4(2) + b
15 = b
y = -4x + 15
Answer:
y= -1/2x - 2
Step-by-step explanation:
To change standard form to slope intercept form, bring the -x to the other side of the equation.
You'll have 2y=-4-x. Since there is no number on the -x, put a 1 on the front of it. (Not necessary). You'll have 2y= -4 -1x
Make y stand on its own. Divide the other side by 2.
You will end up with y= -1/2x -2
