What is the gradient of the graph shown

devlian [24]

The gradient of the graph is 2.

Solution:

Let the points on the graph are (-2, 0) and (0, 4).

Here $x_1=-2, y_1=0, x_2=0, y_2=4$ .

Gradient of the graph:

$$\text{Gradient }= \frac{y_2-y_1}{x_2-x_1}$

$$= \frac{4-0}{0-(-2)}$

$$= \frac{4-0}{0+2}$

$$= \frac{4}{2}$

Cancel the common terms, we get

Gradient = 2

The gradient of the graph is 2.

Help pls dont give just the answer pls step by step so i can understand

Answer:

y=14

Step-by-step explanation:

Since this is an isosceles triangle due to opposite sides being congruent, the base angles would also be congruent.

$50 = 2x \\x=25$

plug in 25 in 2x and you would get 50°

Since the sum of a triangle is 180° you could set up an equation $50+50+5y+10=180$

Then, add 50+50=100+10=110

then you would then have $5y+110=180\\$

subtract 110 from 180, leaving you with 70

$5y=70$

then divide and you would get 14

Check:

5(14)+10+50+50= 180
