Write the equation of a line in slope intercept form given;<br> (6,-3), (0, 5)
olganol [36]

Answer:

y=(-4/3)x+5

Step-by-step explanation:

so you want to start by using y=mx+b

step one: find the slope (remember m is the slope in this)

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

m= \frac{5+3}{0-6}

m= \frac{8}{-6}

m= - \frac{4}{3\\}

step two: insert the value we found for m into the equation and take one of the given points and insert the x and y into the equation (im using (0,5)) and solve for b.

y=mx+b

5= -4/3(0)+b

5=b

step three: rewrite y=mx+b with the values we found for m and for b

y=(-4/3)x+5

What is the value of the function when x = 2?
VARVARA [1.3K]

Answer: The answer is -2

Step-by-step explanation:

To make this easier, first draw or imagine a vertical line at x=2

Find where the vertical line and the graph intersects.

Draw or imagine that point of intersection.

Now, draw or imagine a horizontal line that goes through the point of intersection.

That horizontal line tells us the the value of the function by passing through that mark that says "-2"

The function's value at x=2 is -2.

Kitty [74]

Answer:

Alex baked 9 cherry pies

apple : blueberry : cherry = 1:4:3

apple + blueberry + cherry = 24

1 part: 24 / ( 1+4+3) = 24 / 8 = 3

** Cherry has 3 parts: 3 x 3 = 9

check: apple = 3 x 1 = 3

blueberry: 3 x 4 = 12

12 + 3 + 9 = 24
