Write the equation of the line that passes through the points (7,-6) and (0,2). Put

Alex

Answer:

$y+6=\frac{-8}{7} (x-7)$

Step-by-step explanation:

To find the slope of the equation use $\frac{y_2-y_1}{x_2-x_1}$ .

So, $\frac{-6-2}{7-0}$ = $\frac{-8}{7}$ . Now we can use our slope and any of the two points to write in point-slope form, which is $y-y_1=m(x-x_1)$ . Using the point (7,-6), the formula will give $y+6=\frac{-8}{7} (x-7)$ .

To check, you can plug in this equation and the points into a calculator to graph. The line passes through both points.

Answer:

1) -3a + 24b

2) 5x^2 + 2x +1

Step-by-step explanation:

1) (-a + -a+ -a) + (6b + 8b + 10b)

(-3a) + (24b)

-3a + 24b

2) (2x^2 + 3x^2) + (4x - 2x) + (7-6)

(5x^2) + (2x) + ( 1 )

5x^2 + 2x + 1
