Answer:
2x^2 - 5x - 3 = (2x + 1) (x - 3) IS CORRECT

Step-by-step explanation:

F O I L : Firsts Outsides Insides Lasts

— (2x+ 1) (x - 3) Multiply 2x with x = 2x^2

— (2x + 1) (x - 3) Multiply 1 with -3 = -3

— (2x + 1) (x - 3) Multiply -3 with 2x = -5x

(2x + 1) (x - 3) = 2x^2 - 5x - 3

Answer is CORRECT!

Slope : - 9/7 point : ( -7,4 )

dolphi86 [110]

To form an equation with the given information, we use the formula :

y = mx + b, m being the slope and b being the y-intercept.

Since it is given that the slope is -9/7, we substitute m with -9/7.

y = -9/7x + b

To find b, we will substitute the known coordinates into the equation :
At point (-7 , 4), x = -7, y = 4

4 = -9/7 (-7) + b
4 = 9 + b
b = 4 - 9
b = -5

Now we know that b = -5, we will substitute b = -5 into the equation that we found earlier, y = -9/7 x + b :

y = - 9/7x - 5

To make it more readable, we can multiply the equation by 7:
7y = -9x - 5
7y + 9x + 5 = 0

-----------------------------------------------------------
Answer : 7y + 9x + 5 = 0
