Question 6

In each diagram, line g is parallel to line k, and line t intersects lines g and k. (Click on the picture)

Based on the diagrams, which statement about x is true?

Accepted Answer

The value of x should be 75, because the angles shown in the diagrams are congruent.

Answer

The value of x should be 105, because the measures of the angles shown in the diagrams add up to $$180\degree$$ .

Answer

The value of x should be 140, because the measures of the angles shown in the diagrams should add up to $$360\degree$$ and $$360-\left(110+110\right)=140$$ .

Answer

The value of x should be 70, because the measures of the angles shown in the diagrams are both $$70\degree$$ .

Yes, because the graph shows a straight line.

Question 11

Ms. Hernandez is renting a car for one day. The table shows the total amount she will be charged for the car based on the number of miles she drives.

When these data are graded on the coordinate grid, the points all lie on the same line. What are the slope and y-intercept of this line?

Accepted Answer

Slope = $$\frac{1}{10}$$

y-intercept = $$30$$

Answer

Slope = $$30$$

y-intercept = $$\frac{1}{10}$$

Answer

Slope = $$\frac{1}{2}$$

y-intercept = $$30$$

Answer

Slope = $$30$$

y-intercept = $$\frac{1}{2}$$
