Slope/Gradient
The formula for calculating the gradient/slope:
rise/run or (y2-y1)/(x2-x1)
What is the y intercept of the line y=2x+4
(0, 4)
what is Acrophobia?
Fear of Heights
What is the gradient/slope of the line y=x+4
m = 1
Find the y-intercept of y = 4x - 24.
(0,-24)
What is Botanophobia?
A fear of plants
Find the gradient/slope of the line y=-x+7
m = -1
What is the y intercept of the line y = 3x
(0,0)
What is Zoophobia?
A fear of animals
Find the gradient/slope of the line y = -3/2 x + 10
m = -3/2 or -1.5
what is the y intercept of the line x=2
there is no y intercept
What is Trypanophobia?
Fear of injections/needles
Find the gradient/slope of the line 2y = 4x + 10
m = 2
Find the y intercept of -2x +8y = -8
(0, -1)
What is Ophidiophobia?
Fear of snakes
