Answer:
slope = m = 3/7
y-intercept = b = -5
Step-by-step explanation:
y = mx + b is the slope-intercept form of the equation of a line
where m = slope, and b = y-intercept.
slope = m = 3/7
y-intercept = b = -5
Answer:
-4
Step-by-step explanation:
The slope is the number (& sign) attached to the variable x.
Remember to follow the slope-intercept form: y = mx + b.
Isolate the variable y. Note the equal sign, what you do to one side, you do to the other. ∴
First, add 4x to both sides:
-4x (+4x) - y = -5 (+4x)
-y = 4x - 5
Next, divide -1 from both sides (to make the variably y positive):
(-y)/-1 = (4x - 5)/-1
y = (4x - 5)/-1
y = -4x + 5
Slope intercept form: y = mx + b, in which m = slope, ∴ -4 is your answer.

Answer: Therefore the demand function can be given as;
q = -3/2p + 1590
Step-by-step explanation:
Given that at;
$900 the monthly demand is 240. ....1
$850 the monthly demand is 315. ....2
Since, the function is a linear function. The demand function would be of the form;
q = mp + c ....5
Where q = quantity demanded
p = price m = slope and c = intercept
Substituting conditions 1 and 2 to the equation.
240 = 900m + c. ...3
315 = 850m+ c ...4
Subtracting eqn 4 from 3
-75 = 50m
m = -75/50
m = -3/2
Substituting m = -3/2 into equation 3;
We have,
240= -3/2(900) + c
c = 240 + 3/2(900)
c = 1590
Therefore the demand function can be given as; substituting m and c into equation 5, we have;
q = -3/2p + 1590
