Answer:

the answer is 47

Step-by-step explanation:

you have to look at the y as 7 plug the 7 in the parentheses on the left side of the minus sign and you get 63. Now look at the 4x. X is now replaced with 4. 4 times 4 is 16. 63 minus 16 is 47.

Write an equation in point-slope form of the line that passes through the given point and has the given slope. (3, 2); m = 2/3

77julia77 [94]

Answer:

$y - 2 = \frac{2}{3}(x-3)$

Step-by-step explanation:

Point-slope form: y - y1 = m(x - x1)

Slope: $\frac{2}{3}$

Point: (3, 2) = (x1, y1)

To write the equation in point-slope form, we need to know the values of the slope and one point. Since we've already been given those values, all we have to do is input them into the equation:

y - y1 = m(x - x1)

$y - 2 = \frac{2}{3}(x-3)$

The equation in point-slope form is: $y - 2 = \frac{2}{3}(x-3)$
