A coordinate plane with a line passing through (0, negative 3), (2, 0), and (4, 3). Which equation represents the graphed functi
Talja [164]

Answer:

y=\frac{3}{2}x-3

Step-by-step explanation:

we have the points

(0,-3),(2,0) and (4,3)

step 1

Find the slope

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

we take

(0,-3),(2,0)

substitute the values in the formula

m=\frac{0+3}{2-0}

m=\frac{3}{2}

step 2

Find the equation of the line in slope intercept form

y=mx+b

we have

m=\frac{3}{2}

b=-3 -----> the point (0,-3) is the y-intercept

substitute

y=\frac{3}{2}x-3

The graph in the attached figure

Kamal wrote the augmented matrix below to represent a system of equations.
Sergio039 [100]

Answer:

\left[\begin{array}{cccc}1&0&1&|-1\\-3&-9&3&|27\\3&2&0&|-2\end{array}\right]

Step-by-step explanation:

Given [Missing from the question]

\left[\begin{array}{cccc}1&0&1&|-1\\1&3&-1&|-9\\3&2&0&|-2\end{array}\right]

Required

R_2 \to -3R_2

This implies that, we form a new matrix where the second row of the new matrix is a product of -3 and the second row of the previous matrix.

So, we have:

Initial =\left[\begin{array}{cccc}1&0&1&|-1\\1&3&-1&|-9\\3&2&0&|-2\end{array}\right]

New =\left[\begin{array}{cccc}1&0&1&|-1\\-3*1&-3*3&-3*-1&|-3*-9\\3&2&0&|-2\end{array}\right]

New =\left[\begin{array}{cccc}1&0&1&|-1\\-3&-9&3&|27\\3&2&0&|-2\end{array}\right]
