Answer:
y = 1
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (7, 2) and (x₂, y₂ ) = (0, y)
m = , that is
= ( cross- multiply )
7(y - 2) = - 7 ( divide both sides by 7 )
y - 2 = - 1 ( add 2 to both sides )
y = 1
I can't read all the question but my guess is by half.
Answer:
3 15
-15 18
0 0
Step-by-step explanation:
You can multiply a matrix by a scalar by multiplying each term in the matrix by the scalar
3 * 1 5 3 15
-5 6 -15 18
0 0 becomes 0 0
Answer:
point slope form: y-(-4)=-3(x-1)
Slope intercept form: y=-3x-3
Step-by-step explanation:
Point slope form formula: y-y1= m(x-x1)
(1,-4), (-1,3)
Slope formula x2-x1/ y2-y1
Plug in the information 3-(-4)/-1-1
Simplify: 6/-2 or -3
Use one of the coordinates for the equation: y-(-4)=-3(x-1)
I used the first coordinate.
Slope intercept form formula: y=mx+b
Slope=-3
Plug in information: y= -3x+b
To find b, plug in one of the coordinates.
-4=-1+b, subtract to isolate b
b=-3
Your equation: y=-3x-3
Hope this helps!
