Answer:
Page 3 - the y-intercept would remain at 5 and the slope would be 3 times the upward slope.
Page 5 - the y-intercept would remain at -2 and the slope would be 1/4 instead of 5
Step-by-step explanation:
In point slope form the slope and y-intercept can be read directly from the equation.
y = mx + b where m is the slope and b is the y-intercept.
i) 3a+2b=9 /*3
9a+6b=27
ii) 8x+6y=60 /: 2
4x+3y=30
Answer: 75 ft
45x10 = 450
450/6=75
