Answer:
y = 2x - 13
Step-by-step explanation:
Equation of a line is y = mx + c, m is the gradient and c is the intercept
The line passes through points 4 and -5, x is 4 and y is -5
-5 = 4m + c
When two lines are perpendicular, the products of their gradients are equal to -1, m1 * m2 = -1
x + 2y = 5
2y = -x + 5
y = (-1/2 * x) + 5
therefore m = -1/2
m1 * m2 = -1
m * -1/2 = -1
-m = -2 , therefore m = 2
-5 = 4 * 2 + c
c = -5 - 8, which is -13
Therefore the equation for the line is
y = 2x - 13
Answer:
D
Step-by-step explanation:
eq. of given line is x+y=10
eq. of any line parallel to given line is x+y=a
if it passes through (-1,5) then -1+5=a
or a=4
reqd. eq of line is x+y=4
or y=-x+4
12 liters because 2.75 gallons is not greater then 12 liters.
