What is the equation of the line, in slope-intercept form, that passes through the point (0,7) and is perpendicular to the line y=3x−5?

The line would be y = -1/3x + 7

Step-by-step explanation:

In order to find this, we first need to look at the slope of the original equation, which is 3. Perpendicular lines have opposite and reciprocal slopes, which would make the new line's slope -1/3. Knowing this, we can use the slope and the point in point-slope form to get the equation.

y - y1 = m(x - x1)

y - 7 = -1/3(x - 0)

y - 7 = -1/3x

y = -1/3x + 7

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.
