Answer:
a) y =2/3 x + 7.
b) x = -1
c) y = -4/5 x - 1/5
d) y = -3/2 x + 5/2.
Step-by-step explanation:
a) Intercept form y = mx + b where m = 2/3 and b = 7
b) y can take any value but x is always -1.
c) Slope m = (-1-3)/ (1 - -4)
= -4/5
Using point-slope form where m = -4/5 and x1 y1 = 1 , -1:
y - y1 = m(x - x1)
y - -1 = -4/5(x - 1)
y + 1 = -4/5x + 4/5
y = -4/5 x - 1/5
d) The slope m of the line perpendicular to this line is:
-1 / 2/3
m = -3/2.
When x = -1 , y = 4 so using the slope intercept form of a line
y = mx + b
4 = -3/2 * -1 + b where b = the y-intercept.
4 = 3/2 + b
b = 4 - 3/2 = 5/2.
The equation is y = -3/2 x + 5/2.

Answer: Estimates vary, but each person uses about 80-100 gallons of water per day
Alright here's the breakdown:
it said every 4 miles <span>Vanessa jogged, Cody jogged 3 miles.
so
</span><span>Vanessa jogged 1 mile
that means
Cody jogged .75 of a mile ( or 75% of 1 )
because
Cody will always jog 75% of how much Vanessa joged
so say that
</span><span>Vanessa jogged 50 miles
all you do is take 75% of how much </span>Vanessa jogged
and that should be how much Cody joged
hopes this helps!
