$ax - bx + y = z \\ \Leftrightarrow x(a - b) = - y + z \\ \Leftrightarrow x = - \frac{y - z}{a - b}$

Write the equation of the line that passes through the points (2,−8) and (1,7). Put your answer in fully reduced point-slope for

ValentinkaMS [17]

Point-slope form of equation is: $y - 7 = -15(x-1)$

Step-by-step explanation:

Given points are:

(2,-8) and (1,7)

First of all we have to calculate the slope of the line

so,

$m=\frac{y_2-y_1}{x_2-x_1}\\= \frac{7-(-8)}{1-2}\\=\frac{7+8}{-1}\\=\frac{15}{-1}\\= -15$

Point-slope form is given by:

$y-y_1 = m(x-x_1)$

Putting the value of slope

$y-y_1 = -15(x-x_1)$

We can put any one of two given points in the equation to find the final form of point-slope form

Putting (1,7) in the equation

$y - 7 = -15(x-1)$

Hence, point-slope form of equation is: $y - 7 = -15(x-1)$

Reducing and simplifying

$y - 7 = -15(x-1)\\y-7 = -15x+15\\y-7+7 =-15x+15-7\\y = -15x+8\\15x+y = 8$

Write the equation of a line that passes through the point (-1,5) and has a slope of -7. Your answer should be given in the form

Marysya12 [62]

Plug the values in the equation and find b
(x, y) and m = slope
$5 = ( - 7)( - 1) + b \\ b = - 2 \\ y = - 7x - 2$

Answer:

C. Draw a ray

Step-by-step explanation:

The first step in constructing an angle - or copying one - is to draw a ray. Then, you will use a protractor, compass, straightedge, etc.
