sertanlavr [38]
It is 45% of 247 move the the decimal on the 45% two places to the right, then you should get .45. Of means multiply so .45*247 should get you the answer of 111.15 that's how you find the percent of this number. If you round the answer you would get 111 so about 111cars had a sunroof

What is the slope of the graph?
Dennis_Churaev [7]

Answer:

-4

Step-by-step explanation:

Slope can be found with \frac{y2-y1}{x2-x1}

Pick two points on the graph that the line runs through

(-2, 4) will fill the values of x1 and y1, and (-1, 0) will fill the values of x2 and y2

Insert the coordinates into the formula

\frac{0-4}{(-1)-(-2)}

\frac{-4}{-1+2}

\frac{-4}{1}

Therefore the slope is -4
