Jeremy claims that if a linear function has a slope of the same steepness and the same y-intercept as the linear function in the

graph, then it must be the same function. On a coordinate plane, a line goes through points (0, negative 1) and (2, 0). Which equation is a counterexample to Jeremy’s argument? y = negative one-half x minus 1 y = negative one-half x + 1 y = one-half x minus 1 y = one-half x + 1

Answer: It is only the 3rd equation that is a good example to Jeremy's argument. Others are counter examples to Jeremy's argument.

Step-by-step explanation:

Let us consider the general linear equation

Y = MX + C

On a coordinate plane, a line goes through points (0, negative 1) and (2, 0). 

Slope = ( 0 - -1)/( 2- 0) = 1/2

When x = 0, Y = -1

Substitutes both into general linear equation

-1 = 1/2(0) + C

C = -1

The equations for the coordinate is therefore

Y = 1/2X - 1

Let's check the equations one after the other

y = negative one-half x minus 1

Y = -1/2X - 1

y = negative one-half x + 1

Y = -1/2X + 1

y = one-half x minus 1

Y = 1/2X - 1

y = one-half x + 1

Y = 1/2X + 1

It is only the 3rd equation that is a good example to Jeremy's argument. Others are counter examples to Jeremy's argument.

Answer:

1.25 : 1

0.25 : 1

Step-by-step explanation:

Ratios are basically fractions and proportions

10 : 8 is equal to 10/8 or 1.25/1, so 1.25 : 1

5 : 20 is equal to 5/20 or 0.25/1, so 0.25 : 1

Name the intersection of plane ABC and plane LOD
Alchen [17]

Answer:

segment AD

Step-by-step explanation:

LOD is the far side of the cube.

ABC is the left side.

So the intersection is the vertical EDGE AD, on the far-left.
