y - y1 = m(x - x1) is the general form of the point-slope formula.
Plug in the given values, m = -4, x1 = 7 and y1 = 1 and youll get the answer.
You seemed to have gotten the equation wrong, but don't worry I'll help you
===================================================================
First you simplify the equation
4=<span><span><span>(-1)</span><span>(-3)</span></span>+b
(A negative times a negative is a positive)
</span>4 = 3 + b
(Flip the equation)
b + 3 = 4
--------------------------------------
Then you subtract 3 from each side
<span><span>b+3-</span>3</span>=<span>4-3
</span>b = 1 is your answer
===================================================================
y = -1x - 7 is wrong as well
To find the answer just add -4 on each side for y+4=-<span>1<span>(x-3)</span></span>
<span>y+4+-4</span>=-<span>x+3+-4
</span>y = -<span><span>x - </span><span>1 is the answer
</span></span>To graph, plot points on Y-intercept of -1 and place another point at (-2,1)
Answer:
An additional student came by to inform me that they lost their phone yesterday (he thinks by the bus station). It is an iPhone 13 in a black case. If anyone has come across it, please bring the device to Mr. Velez in room 112 and on behalf of the student, thank you!
Step-by-step explanation:

Given that the roots of the equation x^2-6x+c=0 are 3+8i and 3-8i, the value of c can be obtained as follows;
taking x=3+8i and substituting it in our equation we get:
(3+8i)^2-6(3+8i)+c=0
-55+48i-18-48i+c=0
collecting the like terms we get:
-55-18+48i-48i+c=0
-73+c=0
c=73
the answer is c=73
