ADE and ABC are similar which best explains why the slope of the line between points a and D is the same as the slope between points a and B I ready diagnosticderslerinde başarılar dilerim
The slope-intercept form:

m - slope
b - y-intercept
We have m = 2 and b = 3. Substitute:

54/4 = 13.5
take the 2 whole numbers below 13.5 and the 2 whole numbers above 13.5
12 + 13 + 14 + 15 = 54
the answer to your question is c
