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
First, solve for x. Isolate the x. Do the opposite of PEMDAS.
2x + 4 = 8
Note the equal sign. What you do to one side, you do to the other.
subtract 4 from both sides
2x + 4 (-4) = 8 (-4)
2x = 8 - 4
2x = 4
divide 2 from both sides
2x/2 = 4/2
x = 4/2
x = 2
you know you're starting number now: 2
"then add it to two": 2 + 2 = 4
"then add it to ten": 4 + 10 = 14
"then subtract three": 14 - 3 = 11
"then add ten": 11 + 10 = 21
21 is your final answer
hope this helps
