Y= -5x+3 is the equation that is perpendicular to line AB with the point (1,-2)

The slope of a perpendicular line is the opposite reciprocal of the slope of the line that is given which means that the slope of the perpendicular line in this case is -5. To get the equation of the perpendicular line that goes through the point (1, -2 ) plug in the x and y vales along with the slope you calculated into the point slope formula and solve to get the slope intercept form. 

y-(-2) = -5(x-1)

y=-5x + 3

Work out m and c for the line: ? y = x + 6​
lapo4ka [179]
Well your c value is already there (6) as the standard equation for a line is
y = mx + c

To find the gradient (M) plot two points on the line.

Then label each co ordinate X1 and X2 and then Y1 and Y2

Then subtract your y1 from y2 and then x1 from x2.

For example :if your coordinates were (1,2) (3,4) you would do
4-2 and 3-1

These answers become your “changes” now do change in y / change in x

In terms of the Example you would do 2/2 which would be 1 and the M value would be 1

Hope that isn’t too confusing

Find the value of x.<br><br><br> A. 4.3<br> B. 2.7<br> C. 11.6<br> D. 13.9
kakasveta [241]

Answer:

<h2><u>[D] 13.9</u></h2>

Explanation:

  • <em>Pythagorean theorem: a² + b² = c²</em>
  • <em>Solve for hypotenuse (side x) using: c = √a² + b²</em>

12.8² + 5.3² = 191.93

√191.93

= 13.8538803229

<em>Round the answer</em>

13.9
