Step-by-step explanation:
Answer:
The slope, m = 3; the y-intercept, b=7; and to draw the line on the co-ordinate plane, mark the point where the y-intercept is, b=7. since this is on the y-axis, you plot the ordered pair, (0,7)
Step-by-step explanation:

Answer:
a)
x/25 = 7/2 --> x = 25 * 7/2 = 87.5 miles
b)
x = 45/75 = 0.6 = 60%
c)
x = 1/(1/24 + 1/30) = 13 1/3 minutes
d)
x/2 + x/6 = 12 --> x = 18
Let:
Philadelphia be point a
Pittsburgh be point b
Distance traveled by Michelle be x
Distance traveled by Rich be 305 x
The general formula is:
distance = velocity (time)
substituting the values:
michelle: X = 65(t)
rich: 305 - X = 70 t
substituting both equations gives:
X = 146.562 miles
t = 2.26 hours or 2 hours and 15 mins
