78. Malika earns 7.20 dollars per hour for babysitting. She Baby Sit for 4 hours each week.
Now, she had a total of 12 weeks of working
=> 7.20 * 4 hours = 28.8 dollars
=> 28.8 dollars * 12 = 345.6 dollars.
She spent 10 dollars per week
=> 10 * 12 = 120 dollars
=> 345.6 – 120 = 225.6 dollars is the money that goes to her savings.
Her grandparents put 0.25 times of her money she put on her savings.
=> 225.6 * .25 = 56.4 dollars
=> 225.6 + 56.4 = 282 dollars.
So slope intercept form is y=mx+b m is the slope and b is the y intercept. The equation of this line would be y=1/4x+2 because the rise over run (slope) is 2/8 or 1/4 and the line intercepts the y axis at 2.
