Answer:

90/13, 45/13

Step-by-step explanation:

$- 2 = x \\ 7x + 9y = - 45 \\ \\ 7 \times ( - 2)y + 9y = - 45 \\ y = 9 \\ \\ 7x + 9 \times 9 = - 45 \\ x = - 18 \\ (x.y) = (- 18.9) \\ \\$

Simplify:

$- 2 \times 9 = - 18 \\ 7 \times ( - 18) + 9 \times 9 = - 45 \\ - 18 = - 18 \\ - 45 = - 45$

(01.05) Use the graph below to answer this question: graph of line going through negative 1, 4 and 2, 0 Find the average rate of

dsp73

1) Find the graph of a line passing through (-1, 4) and (2, 0).

The slope of two points can be determined by dividing the difference of y-values by the difference of x-values:

$\frac{4-0}{-1-2} =\frac{4}{-3}$

The slope of this equation is -4/3. Inputting this into the slope-intercept form of an equation, we get:

$y=\frac{-4}{3} x+b$

To find b, substitute x and y for one of the given coordinate pairs:

0 = (-4/3)(2) + b

0 = -8/3 + b

8/3 = b

Substitute the b value into the equation to finish the line:

$y=\frac{-4}{3} x+\frac{8}{3}$
