Equation for (-2,-5) and (1,-3) in slope-intercept form

Answers

Answer:

y=2/3x-11/3

Step-by-step explanation:

First, find the slope.

m= y2-y1/x2-x1

-3+5/1+2 = 2/3

Slope is 2/3

Now, pick one of the coordinates and use that and the slope to put it in point-slope form.

Point slope form: y-y1=m(x-x1)

Let's use (1,-3)

y+3=2/3(x-1)

Distribute 2/3 to (x-1) and simplify to get the equation in slope-intercept form.

y+3=2/3x-2/3

y=2/3x-11/3

Answer:

y=2/3x-11/3

Step-by-step explanation:

use slope formula and slope intercept form. y=mx+b

Henry is using a total of 16 ft. of lumber to make a bookcase. The left and right sides of the bookcase are each

3(b,a) b-coordinate, a-coordinate
4(y, x) y-coordinate, x-coordinate

Answers

2 as the 4 is referring to the x-axis and y to the y-axis

Lets use process of elimination

Step-by-step explanation:

1. The order of the coordinate grid is like the alphabet. a comes before b,  x comes before y.

2. Step 1 This eliminates 3 and 4. So we are left with 2 and 1.

3. It is not 1 because there is no a and b coordinate. There is only a Y and x one.

4. 4 is on the x axis, 6 is on the y axis.

5. Thus, the answer is 2.

  89.1 liters

Step-by-step explanation:

"At the same rate" means miles and liters are proportional. The unknown is liters, so we can write the proportion with liters in the numerator:

  liters/miles = x/672 = 49/369.6

Multiplying by 672, we have ...

  x = 672(49/369.6) ≈ 89.09091

It will take 89.1 liters of gas to go 672 miles.
