Graph the line of the equation x4+y=−2 using its slope and y-intercept
k0ka [10]

Answer:

y-intercept = c = -2

slope = y = - 4

Step-by-step explanation:

The correct equation is:

4x + y =  -2

We need to graph the line using its slope and y-intercept. The slope intercept form of the equation is:

y = mx + c

Here, m is the slope and c is the y-intercept. Transforming the given equation to this form gives us:

y = - 4x - 2

This means, the slope is:

m = - 4

and y-intercept is:

c = - 2

y-intercept in ordered pair is written as (0, c). So for the given case the y intercept will be (0, -2). This gives us first point on the graph.

The slope tells us that by how many units will the y variable will change for one unit change in x-axis.

So slope, m = - 4, tells us that the y-variable will change by negative 4 units for 1 unit change in x variable.

Based on this change, we can get another point from (0, -2) which will be (0+1, -2 - 4) = (1, - 6)

This gives us the second point on the graph. Plot these two points and join them using a straight line. This straight line will be the graph of equation y = 4x - 2 or 4x + y = -2

The graph is attached below.

The lengths of two sides of the isosceles triangle are the ratio of 6:5. The perimeter of the triangle is 32cm. What is the area
Degger [83]
Sorry I'm late! xx
Okay, so two of the sides in an isosceles triangle are of the same length. The lengths are either in the ratio 5:5:6 or 5:6:6
The perimeter is 32 cm

If we take the first ratio, 5:5:6, then we have 16 "parts". Let the length of each "part" be referred to as "x"
So, 16x = 32, and so x = 2

So, the ratio of the sides are 10 cm, 10 cm, 12 cm.

To find the height, "h", we need to use Pythagoras' Theorem, with 10 being the hypotenuse and 6 being the horizontal side (think of a line cutting straight down the middle of the isosceles triangle)
h^2 + 36 = 100
h = 8 cm

Area of a triangle is 0.5 x base x height. So, 0.5 x 12 x 8 = 48 cm^2

Hope I helped!! xx
