Then the two solutions of the quadratic equation are 4/5 and 3.

<h3>How to solve the equation?</h3>

Here we want to solve the quadratic equation:

(-5x + 4)*(x - 3) = 0

The two solutions are the values of x for which each parenthesis becomes equal to zero, so the two solutions are given by:

-5x + 4 = 0

x - 3 = 0

If we solve these two equations we get:

x = -4/-5 = 4/5

x = 3

Then the two solutions are 4/5 and 3.

Find the value of y so that the line passing through the two points have the given slope (2,3) (7,y) m=-2/5
Liono4ka [1.6K]

Answer:

y = 1

Step-by-step explanation:

Find the slope of the line passing through the points (2,3) and (7,y):

m=\dfrac{y-3}{7-2}=\dfrac{y-3}{5}

The slope of the line is equal to

m=-\dfrac{2}{5},

then

\dfrac{y-3}{5}=-\dfrac{2}{5}\\ \\y-3=-2\\ \\y=-2+3\\ \\y=1
