Drag and drop numbers into the equation to complete the equation of the line in slope-intercept form.
lara31 [8.8K]

Answer:

y = 4x - 15

Step-by-step explanation:

Find slope (m) using of the line that passes through (7, 13) and (4, 1).

slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{1 - 13}{4 - 7} = \frac{-12}{-3} = 4

Find y-intercept (b) by substituting x = 4, y = 1, and m = 4 in y = mx + b.

Thus:

1 = (4)(4) + b

1 = 16 + b

Subtract 16 from each side

-15 = b

b = -15

substitute m = 4, and b = -15 in y = mx + b, to get the equation.

The equation of the line would be:

✅ y = 4x + (-15)

y = 4x - 15

Combine like terms.
coldgirl [10]

Answer:

To solve the question the answer is 35y2 - 5 (i think)

Step-by-step explanation:

Yes and it's actually very simple.

To start off:

Simplify the equation: multiply 7 by the numbers in the parentheses getting: 28y2 - 35 .......full equation: 7y2 + (28y2 - 35)

New equation: 7y2 + (28y2 - 35) now combine like terms this means adding each common variable together. in this case, 7y2 and 28y2 would be added together to simplify the equation. Add them together, the new equation is: 35y2 - 5

Lmk if you have any questions i hope this helps
