When you're graphing a line in slope-intercept form (y = mx + b), your first step is to look at b, which is your y-intercept. The y-intercept is where your line touches the y-axis.
Slope-intercept form is y = mx + b, but for y = -5x doesn't have a b, so you have to add one. You can do this by adding + 0 to the end, since it won't change your equation.
y = -5x + 0
b = y-intercept = 0
m = slope = -5
So, your line will start at 0 on the y-intercept, which will be at the origin point (0,0).
Your slope is -5, or 
, so you'll go down 5 and then to the right 1.
A few points on your line should be (0,0), (1,-5), and (-1,5).
Answer:
197.92 cm
Step-by-step explanation:
The formula to find volume for a cylinder is V=πr^{2}h
The problem gave you the height (h): 7cm and the radius (r): 3cm and pi (π) is a constant that will automatically insert when you use the "π" button in a calculator
Now that you know that you have all your variables, you can now plug them into your formula.
V=π3^{2}7
Next, solve the equation.
V=π(9)(7)
V=π(63)
V=197.92cm
Hope this helped! :)
Answer:
a = -2
b = 7
Step-by-step explanation:
5a+3b=11
-2a+3=b
substitute for b:
5a + 3(-2a + 3) = 11
5a -6a + 9 = 11
-a = 2
a = -2
b = 7
Answer:
Quadrilateral
Parallelogram
Rectangle
Step-by-step explanation:
Graph the shape, either on paper or using a website like Desmos. The shape has four sides, four right angles, and two pairs of congruent sides
