1. A line passes through (1, -5) and (-3, 7). a. Write an equation for the line in point-slope form.
b. Rewrite the equation in slope-intercept form.
А

y-5=
1
(x + 1); y ==x+
3

3
B y- 5= 3(x + 1); y = 3x + 8
C y + 5 = -3(x - 1); y = -3x - 2
D
8
y-1 =
1 = $(x + 5): y = x+
3

Step-by-step explanation:

The slope is -3

You can now substitute (1,-5) for x and y

-5= -3+b  

b=-2

So in slope intercept form the answer is y=-3x-2

In point slope form the answer is 3x+y=-2

step-by-step explanation:

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
