Answer:

Step-by-step explanation:

First, you need to find the slope of the line. To do this you need to choose two points on the graph. The points you are given are (-2, 1) and (4, 6). Then use these to find the slope.

m=\frac{y2-y1}{x2-x1}

m=\frac{6-1}{4-(-2)}

m=\frac{5}{6}

You can then plug this and one of your chosen points into the slope-intercept formula

y-y=m(x-x)

y-1=\frac{5}{6} (x-(-2))

y-1=\frac{5}{6} x+\frac{5}{3}

y=\frac{5}{6}x+\frac{8}{3}

Choose the point slope form of the equation below that represents the line that passes through the points (-3, 2) and (2, 1)
mihalych1998 [28]

Answer:

\large\boxed{y-1=-\dfrac{1}{5}(x-2)}

Step-by-step explanation:

The point-slope form of a line:

y-y_1=m(x-x_1)

m - slope

(x₁, y₁) - point

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (-3, 2) and (2, 1). Substitute:

m=\dfrac{1-2}{2-(-3)}=\dfrac{-1}{5}=-\dfrac{1}{5}

y-1=-\dfrac{1}{5}(x-2)

A mother earned $​8750.00 from royalties on her cookbook. She set aside​ 20% of this for a down payment on a new home. The balan
Masteriza [31]

The problem statement is not clear regarding which money is invested. We will assume it is the 80% of $8750 that is set aside for future education. That amount is

... 0.80 × $8750 = $7000

If x represents the amount invested at 7%, then the total interest earned is

... (7000 -x)×4% + (x)×7% = 420

... 280 +0.03x = 420

... x = 140/0.03 ≈ 4666.67

$4666.67 was invested at 7%.

$2333.33 was invested at 4%.

4x-5(x-2)=12x+4-x<br> ??????????????
Anestetic [448]
     4x - 5(x - 2) = 12x + 4 - x
4x - 5(x) - 5(-2) = 12 - x + 4
    4x - 5x + 10 = 11x + 4
            -x + 10 = 11x + 4
          <u>+ x             + x       </u>
                    10 = 12x + 4
                    <u>- 4            - 4</u>
                      <u>6</u> = <u>12x</u>
                     12    12
