Answer:
(0,9) and (18,0)
Step-by-step explanation:
To find the x-intercept, set y = 0. Note how this equation x + 2y = 18 becomes x = 18. Thus, the x-intercept is (18,0).
To find the y-intercept, set x = 0. Then 2y = 18, and y = 9. The y-intercept is (0,9).
Answer: y = -2x - 5
Step-by-step explanation:
The condition for parallelism is that m1 = m2 ie, the gradient of the two lines must be equal.
from the equation given,
y = -2x + 8, m1 = -2, therefore m2 = -2. Since the two line passes through the coordinate of (-1, -3 ) , we substitute for x and y in the equation of a line
y = mx + c to get the value of , the y - intersect.
-3 = -2 x -1 + c
-3 = 2 + c
solve for c
c = -3 - 2
c = -5.
now , to have the equation of the line , we put c = -7 into the equation
y = mx + c
y = -2x - 5
Therefore the equation of the line parallel to the line
y = -2x + 8 is
y = -2x - 7
Answer:
m=-2
Step-by-step explanation:
The two given points are: (-3, -2) and (-2, -4)
The equation for slope is m=
m=
m=-2/1
m=-2
Answer:
4(x-4.5)^2
Step-by-step explanation:
h(x)=4x^2-36x+81
=4(x^2-9x)+81
=4(x^2-9x+20.25)-(4)(20.25)+81
=4(x-4.5)^2
