I currently don’t have any paper on me to graph it for you, but I am able to give you coordinates.

Explanation:

When given an equation in the form y=Mx+b, we can immediately get the x-intercept and y-intercept.

To get the x intercept:
Make y=0

0=-3x-6
-2=x

So your coordinates are (-2;0)

To get the y intercept:
It is the b value

y=-6

So your coordinates are (0;-6)

Plot those on your graph and draw a line through them, write the equation next to the line and put an arrow on either end of the line.

Hope this helps! Feel free to comment for any questions you may have.

Answer:

14

Step-by-step explanation:

a = 3

b = 4

b(a + 4)-3(3 + 2)+3 - 2\\a = 3,b=4\\4(3+4)-3(5)+3 - 2\\4(7)-15+3 - 2\\28-14\\\\14

find the slope of the line containing the points (-1,6) and (3,5) put final.answer in slope-intercept form
Ugo [173]

Given the points (-1,6) and (3,5).

The formula to find the slope is

m=\frac{y_2-y_1_{}}{x_2-x_1}

Take

x_1=-1,y_1=6,x_2=3,y_2=5

Plug the values into the formula and find the slope.

\begin{gathered} m=\frac{5-6}{3-(-1)} \\ =\frac{-1}{4} \end{gathered}

The slope-intercept form is y = mx+b.

Plug the value of m.

y=-\frac{1}{4}x+b

ThusConsider the point (-1,6). Substitute -1 for x and for y into the equation.

\begin{gathered} 6=-\frac{1}{4}(-1)+b \\ =\frac{1}{4}+b \\ b=6-\frac{1}{4} \\ =\frac{23}{4} \end{gathered}

Thus, the equation of the line in slope intercept form is

y=-\frac{1}{4}x+\frac{23}{4}
