8. Change the equation from standard form to slope-intercept form by solving for y. 8x−4y=24 Determine who changed the equation correctly: Bob: Subtract 8x from both sides: −4y=−8x+24 Divide by -4 on both sides: y=2x−6 Bill: Subtract 8x from both sides: −4y=16x Divide by -4 on both sides: y=−4x Bud: Subtract 8x from both sides: −4y=−8x+24 Divide by -4 on both sides: y=2x+24 (1 point) Responses Bill Bill Bob Bob None of them are correct None of them are correct Bud
The correct answer is:
Bob: Subtract 8x from both sides: -4y = -8x + 24
Divide by -4 on both sides: y = 2x - 6

Suppose that the water level of a river is 45 feet after 3 days of no rain and 10 feet after 10 days of no rain. Given the two points we know: (3, 45) and (10, 10), what would the point slope equation look like?(1 point) Responses (y−45)=−5(x−3) open paren y minus 45 close paren is equal to negative 5 times open paren x minus 3 close paren (y−10)=−5(x+10) open paren y minus 10 close paren is equal to negative 5 times open paren x plus 10 close paren (y−3)=−5(x−45) open paren y minus 3 close paren is equal to negative 5 times open paren x minus 45 close paren (y+10)=−5(x−10)
The point-slope equation would look like:
(y - 45) = -5(x - 3)
13. Suppose that the water level of a river is 45 feet after 3 days of no rain and 10 feet after 10 days of no rain. The river was 60 feet before the drought began.(4 points)
WHATS THE Y-INTERCEPT
WHATS THE RATE OF CHANGE (SLOPE)
WRITE AN EQUASION FOR THIS SENARIO IN SLOPE-INTERCEPT FORM
WRITE AN EQUASION IN STANDARD FORM
The y-intercept represents the initial water level before the drought began. In this scenario, the y-intercept is 60 feet.
The rate of change, or slope, represents the change in water level per day. We can calculate the slope by taking the difference in y-values (change in water level) divided by the difference in x-values (change in days).
Slope = (10 - 45) / (10 - 3) = -35 / 7 = -5.
Therefore, the rate of change is -5 feet per day.
To write the equation in slope-intercept form (y = mx + b), we can use the y-intercept and the slope:
y = -5x + 60.
To write the equation in standard form (Ax + By = C), we can multiply both sides of the equation by -1 to make the coefficient of x positive:
5x + y = 60.
is that relationship proportional?
No, the relationship between the water level and the number of days without rain is not proportional. If the relationship were proportional, the rate of change (slope) would remain constant. However, in this scenario, the rate of change is not constant.
