We will be using the Point Slope formula which is y-y_{1} =m(x-x_{1} )

The information we are given is that m = -4 and the point is (2,-5), so we can input it into the equation.

y- (-5) = -4(x-2)

This simplifies into y+5 = -4x +8

Then we can subtract 5 from each side to get the answer:

y = 4x+3

2. What is an equation line that pass-cs through the point (3,-1) and h (4)
joja [24]
Y=mx+b
m=slope
b=y intercept
we are given (3,-1)
one solution is x=3 and y=-1 or
when x=3 then  y=-1
also slope=2
so
y=2x+b
subsitue 3 for x and -1 for y and solve for b
-1=2(3)+b
-1=6+b
subtract 6
-7=b

y=2x-7 is equation


answer is number 4
