I think that since it says that f:x is |3x-7| and for i. it is f(-1), I believe it is suggesting/telling that x=-1 or f(-1) so |3*(-1)-7|. I don't know for sure but I believe it is 10.

Which one would the equation be?
aleksley [76]

Answer:

a. y = \frac{2}{5}x - 6

Step-by-step explanation:

The slope-intercept form of equation of a line is given as y = mx + b. Where,

m = slope

b = y-intercept.

Rewrite the equations, 2x - 5y = 12 and 4y + 24 = 5x, in the slope-intercept form by making y the subject of the formula. Then, derive our new equation that has the same slope as the first equation, and the same y-intercept as the second equation.

2x - 5y = 12

2x - 12 = 5y

Divide both sides by 5

\frac{2x - 12}{5} = \frac{5y}{5}

\frac{2x}{5} - \frac{12}{5} = y

Rewrite

y = \frac{2x}{5} - \frac{12}{5}

The slope of 2x - 5y = 12 is ⅖.

4y + 24 = 5x

4y = 5x - 24 (subtraction property of equality)

Divide both sides by 4

\frac{4y}{4} = \frac{5x - 24}{4}

y = \frac{5x}{4} - \frac{24}{4}

y = \frac{5x}{4} - 6

The y-intercet of 4y + 24 = 5x is -6

Therefore, the equation that has the same slope as the first equation and the same y-intercept as the second equation would be:

y = mx + b

Plug in the values of m and b

y = \frac{2}{5}x + (-6)

y = \frac{2}{5}x - 6
