Y intercept means the y-coordinate of the point where the graph crosses the y-axis.
Given equation is:
Let x be 0, as at the y-intercept point, the x-coordinate of that point is always 0.
y=
Slope-intercept form is y = mx + b
where m is the slope of the line and b is the y-intercept of the line {the number without a variable}
-2x+6y = 5
6y = 2x+5
y=
Hence, slope is
Answer:
x=29/2
Step-by-step explanation:
In the given expression ( f(x) = 2x² + 1 ) when when ( x = 3 ), the value of f(x) is 19.
Hence D)19 Is the correct answer.
<h3>What is an Equation?</h3>
An equation is simply a mathematical formula that expresses the equality of two expressions, using the equals sign as a connection between them.
Given that;
f(x) = 2x² + 1, what is (fx) when x = 3
We substitute 3 for x in the equation
f(x) = 2(3)² + 1
f(x) = 2(9) + 1
f(x) = 18 + 1
f(x) = 19
In the given expression ( f(x) = 2x² + 1 ) when when ( x = 3 ), the value of f(x) is 19.
Hence D)19 Is the correct answer.
