Answer:
x intercept is -3
Step-by-step explanation:
We need to find the equation for the line
First we find the slope
m = (y2-y1)/(x2-x1)
= (2- -4)/(6- -3)
= (2+4)/(6+3)
=6/9
= 2/3
The we can write the equation
y= mx+b
y = 2/3x +b
We can substitute in (6,2)
2 = 2/3(6) +b
2 =4+b
Subtract 4 from each side
2-4 =b
b =-2
y = 2/3 x-2
We want to find the x intercept, so set y =0 and solve for x
0 = 2/3x -2
Add 2 to each side
0-2 = 2/3x
Multiply each side by 3/2 to isolate x
-2 *3/2 = 2/3x * 3/2
-3 =x
The x intercept is -3
Answer:
The equation in point-slope form is:
Step-by-step explanation:
Write the equation of the line that passes through the points (-3,-8) and (6,-4)
The point slope form is:
Where m is slope and x₁ and y₁ are the points given
Finding Slope
Slope can be found of given points using formula:
We have
Putting values and finding slope
So, slope m = 4/9
Using point (-3,-8) and slope m = 4/9 the equation is:
So, the equation in point-slope form is:
Answer: x = 2
Step-by-step explanation:
The rule for reflecting over x = 2 is that y remains the same and you add how many units x = 2 is from the point.
x = 2 is has the coordinate of x = 2 and y = the y coordinate of the point.
A (-1, 1) Since the y coordinate of (-1, 1) is 1, x = 2 - (2, 1)
Add 3 units to 2, the x coordinate since -1, 1 is 3 units from 2, 1
2,1 --> 5, 1
I really didn't know how to explain but Im 100% sure Im right and I hoped this helped somehow.
