What is the slope, m, and the y-intercept of the line that is graphed below?
Brums [2.3K]

Answer:  The correct option is

(A) m = 1; (0, 3).

Step-by-step explanation:  We are given to find the slope, m, and the y-intercept of the graphed line.

We know that

the slope of a line passing through the points (a, b) and (c, d) is given by

m=\dfrac{d-b}{c-a}.

From the graph, we note that the line passes through the points (-3, 0) and (-1, 2).

Therefore, the slope of the graphed line will be

m=\dfrac{2-0}{-1-(3)}=\dfrac{2}{2}=1.

Also, at x = 0, the value of the y-coordinate is 3. So, the y-intercept of the line is (0, 3).

Thus, the slope, m = 1  and the y-intercept is (0, 3).

Option (A) is CORRECT.

Need help don’t understand
Xelga [282]

Answer:

2 real solutions

Step-by-step explanation:

To determine the nature of the solutions use the discriminant

Δ = b² - 4ac

• If b² - 4ac > 0 then 2 real solutions

• If b² - 4ac = 0 the 2 real and equal solutions

• If b² - 4ac < 0 then no real solutions

Given

x² + 9x + 20 = 0 ← in standard form

with a = 1, b = 9, c = 20, then

b² - 4ac

= 9² - (4 × 1 × 20 ) = 81 - 80 = 1

Since b² - 4ac > 0 then there are 2 real solutions

4z - 9 = 2z

4z -4z -9 = 2z -4z

-9 = -2z

-9 ÷2 = 2z ÷2

Z = 4.5
