Question

(8,5); perpendicular to 2x - y = 7

Answer 1

Answer:

brainliest plzzz

Step-by-step explanation:

2x - y = 7 is in standard form, and if it were slope-intercept form that would help you. I got the y term by itself:

y = 2x - 7 slope-intercept form. You already know the slope of the perpendicular line is the *negative reciprocal* of the slope you have. So that's (-1/2). The perpendicular line is something like

y = -(1/2)x + b and if you substitute 8 for x and 5 for y you get 9 for b.

y = -(1/2)x + 9 is your perpendicular line. In slope-intercept form. To get back to standard form, start by getting rid of fractions. Multiply both sides by 2.

2y = -x + 18 then add x to both sides.

x + 2y = 18 done.
