Answer:
B. y= -4x + 28
Step-by-step explanation:
To find the equation of this line first put it into slope-point form, where and are the y and x coordinates and m is the slope. So plug in the information to get the equation, y-8=-4(x-5). Then solve for y,
First, distribute the -4
y-8=-4x+20
Next, add 8 to both sides
y=-4x+28
Add or subtract like terms
2x+3y=5x-y
7x=2y
since you can’t divide or add any more like terms together there isn’t anything else to solve
answer ~ 7x=2y
