Write the line equation for the line passing through the points (8, 3) and (12, -1).

type the product of the slope and the y-intercept, rounded to the nearest tenth.

• provide an explanation •

Line equation is y=-x+11

The product of the slope and the y-intercept is -11

Step-by-step explanation:

Use the slope formula to find the slope of the equation.

yvalue2 minus yvalue1 /xvalue 2 minus xvalue1

-1-3/12-8=-1

The slope is -1.

Now, use the slope-intercept formula to find the y-intercept

y-3=-1(x-8)

y-3=-x+8

y=11

The equation is y=-x+11

The product of the slope and the y-intercept is -1(11)=-11

Hope this helps.

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

1) is right
