Write the equation of the line yhat is perpendicular to 5x+8y=16 and passes through (-5,7)
1 answer:
Answer:
or
Step-by-step explanation:
To write the equation, convert the line to slope intercept form to find the slope.
5x+8y=16
8y=16-5x
y=-5/8 x +2
The slope of this line is -5/8. The slope of the line perpendicular to this line will be the negative reciprocal or 8/5.
Write the equation using the slope m=8/5 and the point slope form.
This is the equation of the line. You can convert it to slope intercept form:
