if I have a question on my work that says solve the equation how could I solve this one, (7,-6): m = -4 ..... im not really sure
Nimfa-mama [501]

Answer:

y= -4x+22

Step-by-step explanation:

slope= -4

-6=-4(7)+b

-4x7=-28

-6=-28+b

28-6=22

so the equation would be y= -4x+22

b=y-intercept

mx=slope multiplied by x
