Look at the picture.

The point-slope form:

$y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (-3, -3) and (2, 0). Substitute:

$m=\dfrac{0-(-3)}{2-(-3)}=\dfrac{3}{5}\\\\y-0=\dfrac{3}{5}(x-2)\qquad|\text{use distributive property}\\\\y=\dfrac{3}{5}x-\dfrac{6}{5}\qquad|\cdot5\\\\5y=3x-6\qquad|-5y\\\\0=3x-5y-6\qquad|+6\\\\3x-5y=6$

Answer:

point-slope form: $y=\dfrac{3}{5}(x-2)$

slope-intercept form: $y=\dfrac{3}{5}x-\dfrac{6}{5}$

standard form: $3x-5y=6$

On Friday Alexis bought 7 T shirt for 18 each she also bought 4 sports caps for 14 each and a pair of shoes for 26. How much mon

aivan3 [116]

We have to multiply 7 by 18 to find out how much she spent on t-shirts.
7 × 18 = 126

We multiply 4 by 14 to find out how much she spent on caps.
4 × 14 = 56

Now we add 126 (shirts) and 56 (caps) and 26 (shoes).

126 + 56 + 26 = 208 she spent on Friday
