Answer:

y = (-1/4)x + 4 is the equation of the line in slope-intercept form.

Step-by-step explanation:

When graphing the line I like to do it from left to right. Start at the point (0,4) which is the y-intercept as a coordinate. Slope is rise over run so now go down 1 unit and 4 units to the right. Keep doing that pattern and then connect the points to form a line. Make sure to put arrows on the ends to represent that the line goes on forever in both directions. Going right to left you could go up 1 unit and 4 units to the left as well. I hope this helps.

Solve 1/2x + 3 > 2(x-5/2)

Likurg_2 [28]

Answer:

1/4x (8 x - 15)

Step-by-step explanation:

write the division as a fraction

1/2x + 3/2x (x - 5 ÷ 2)

factor out 1/2 from the expression.

1/2x(x + 3(x - 5 ÷ 2))

divide the numbers.

1/2x(x + 3(x - 2.5))

distribute 3 through the parentheses.

1/2x(x + 3x - 7.5)

collect like terms.

1/2x(4x - 7.5)

1/2x(4x - 15/2)

factor out 1/2 from the expression.

1/2 x 1/2 x (8 x - 15)

multiply the fractions

= 1/4 x (8x - 15)

or alternative form

= 0.25(8x - 15)
