Answer:
- (1,-3), (2,-2)
Step-by-step explanation:
The graph passes through (3, -1) and (0, -4)
<u>The slope is:</u>
- (-4 - (-1))/-3 = -3/-3 = 1
<u>The y-intercept is given</u>: -4
<u>The line is:</u>
- y = x - 4
See the graph
<u>The points plotted as well and those on the line are:</u>
- (1,-3)
- (2,-2)
The solutions for the quadratic equation are given as follows:
x = -1, x = 7/5
<h3>What is a quadratic function?</h3>A quadratic function is given according to the following rule:
y = ax^2 + bx + c
The solutions are:
In which:
For this problem, the equation is:
5x² - 2x - 7 = 0.
Hence the coefficients are a = 5, b = -2 and c = -7, and then the solutions are found as follows:
The solutions are:
x = -1, x = 7/5
