Answer:

a=7.9

Step-by-step explanation:

2.25(a+1.3)=20.7 *Distribute (multiply) the 2.25 throughout the parenthesis

2.25a+2.925=20.7 *Subtract 2.925 from both sides

2.25a=17.775 *DIvide by 2.25

a=7.9

Answer:

In order to find the slope, you need to find the difference in the x values and the difference in the y values. To do this, you write out y2-y1/x2-x1, insert your x and y values, and get your answer. Then, you find your y-intercept (where the x value is 0).
