Does blood pressure increase with age? A group of researchers want to know if systolic blood pressure increases with age. They designed an experiment where they took a random sample of 8 individuals and measured their systolic blood pressure and recorded their age. The data is presented in the table below:
Systolic Blood Pressure (mmHg)
Age (years)
128
58
141
74
123
47
140
58
121
33
134
47
120
30
119
23

Find the equation of the line that goes through the points (4, –1) and (2, –5). use slope formula, equation, to find the slope of a line that passes through the points. m = use slope-intercept form, y = mx + b, to find the y-intercept (b) of the line. b = write the equation in slope-intercept form, y = mx + b.
