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.
