y2-y1/x2-x1
Gradient Formula, how to find slope when given two points
Gradient
The steepness of a line, represented by the letter m
Y= mx + b
Gradient-Intercept form of a linear equation where m represents the slope and b represents the y-intercept
Rate of Change
Term that means the SAME THING AS GRADIENT that we find by using the equation Y2-Y1/X2-X1
x-intercept
The point on a graph where a function crosses the x-axis (Where Y=0)
y-intercept
The point on a graph where a function crosses the y-axis (Where X=0), also called b
Coordinate Plane
The four quadrants of a graph where we plot points and graph lines
Steepness
Refers to the incline of the gradient of a line
Parallel
When lines have the same slope and will never cross (slopes are the same)
Perpendicular
When lines intersect at a 90 degree angle (slopes are opposite reciprocal)
positive gradient
a line that goes up from left to right
Negative gradient
a line that goes down from left to right
No gradient
a line that goes horizontal
Undefined gradient
a line that goes vertical
Coordinate Pair
A point on the coordinate system (x,y)
Has a gradient of 5 and y-intercept of -3
y = 5x-3
Gradient = -2 and y-intercept of 3
y + 2x = 3
