Find the equation for the line that passes through the point (1,3), and that is perpendicular to the line with the equation y +
Marianna [84]

Step-by-step explanation:

the slope of a line function is always the factor of x.

in our case : -1/4

it is the ratio y/x indicating how many units y changes, when x changes a certain amount of units.

in our case y decreases by 1 for every x increase by 4.

now, the perpendicular slope simply changes x and y upside-down and flips the sign.

in our case it is : 4/1 = 4

so, the line function in point slope form is then (using the new slope and the point coordinates)

y - 3 = 4(x - 1)

Find a, (x-3) + (x-a) = 15
slega [8]

a = 2x - 18

remove the parenthesis and simplify

x - 3 + x - a = 15

2x - 3 - a = 18 ( add 3 to both sides

2x - a = 18 ( subtract 2x from both sides )

- a = 18 - 2x ( multiply through by - 1 )

a = - 18 + 2x

a = 2x - 18
