Pls do fast within 5 minutes and i will give like for sure SOLUTION MUST BE IN TYPED FORM
SECTION 1.4: POINT-SLOPE FORM OF EQUATION OF THE LINE
Slope Intercept form: y = mx + b where m is the slope and b is the y-intercept
Point Slope Form: y-y₁ = m(x-x₁) where m is the slope and the line passes through (x₁.₁)
1) Find an equation for the line that passes through the given points (0,2) and (2,3)
2) Determine the slope and the y-intercept of the equation 7y + 12x - 2 = 0
3) During the early years of the Olympics, the height of the men's winning pole vault increased
approximately 8 inches every four years. The following table shows that the height started at 130 inches
in 1900, and increased by the equivalent of 2 inches a year between 1900 and 1912
Year
1900 1904 1908 1912
Height (inches) 130 138 146 154
a) Does this table represent a linear function? Explain. If it does, find the slope of the linear function.
b) Write the equation of the line in point-slope form to model the height of the men's winning pole
vault since 1900,
c) Use the answer in part (b) to find the equation of the line in slope-intercept form.
