What is the equations of a straight line 2y equals 5x plus 8 what s the gradient of the straight line and coordinates of the intercept on the y-axis?

The gradient of a line is its slope, rather than a magnitude of change in a scalar field. Therefore:
2y = 5x + 8
Divide by 2:
y = 5/2 * x + 4
This means that it has:
Slope (gradient): 5/2
y-intercept: (0, 4)
x-intercept: (-1.6, 0)
(0,4) (the origin) is the y-intercept.

What are linear formulas?
A linear equation is y = mx + c where m is the gradient and c is the y-intercept. Linear equations are always graphically shown as a straight line, regardless of the gradient or the y-intercept.
What is -2x plus y equals -4?
-6
Where is the y-intercept of any direct variation equation?
As for example in the straight line equation: y = 3x+5 the y intercept is 5 and the slope or gradient is 3
What do graph you get if you make both the angle and the distance parameters in an equation?
You get a graph based on polar coordinates rather than Cartesian coordinates. Some shapes have simpler equations in polar coordinates: for example, a circle with centre at the origin and radius r, is simple R = r. A straight line through the origin and gradient (slope) m is tan(q) = m.
What equations describe a straight line with a y-intercept of 7?
Y = ('x' times any number) + 7

How do you find y-intercept?
The y-intercept can be obtained from the straight line formula, y=mx+c. The y-intercept, c, is therefore given by c=-mx+y where m is the coefficient of gradient.

What is 17x plus 2y equals 23?
17x + 2y = 23 is the equation of a straight line with gradient -8.5 and intercept 11.5
What is the slope -1 3 y-intercept 3?
Two coordinates are needed to determine the slope of a straight line equation.
How do you write an equation in slope-intercept form of the line passing through each pair of points?
y=mx+c where x and y are variables, m is the gradient (or slope) and c is the intercept on y (axis). that is the general equation of a straight line. if you had given some coordinates for the points one could extrapolate from that to find the full equation. since you have not, one cannot.
What would a mapping diagram for 3x plus 2 be?
It would be a straight line with gradient 3, which would intercept the y axis at the point (0,2).
Who introduced system of equations with coordinate axes?
It was the Frenchman Rene Descartes who intoduced straight line equations in the form of y = mx+c whereas m is the slope and c is the y intercept
What can you say about the graph Ax plus By equals C about the graph Ax plus By equals C?
It is a straight line with gradient -A/B and intercept C/B.
