Any straight line on an x- and y-coordinate graph can be described using the equation y = mx + b. The x and y term refer to a specific coordinate point on the graphed line. The m term refers to the slope of the line or the change in the y-values with respect to the x-values ...
wheremis the slope of the line After we have the slope of the line, then the equation of the line is written by using the point-slope formula as shown below- y−y1=m(x−x1) The equation of a line in the slope-intercept form- ...
A function whose graph is a straight line is called a linear function. A function is linear if its equation can be expressed in the form f(x)=mx+b where m is the slope and b is the y-intercept of the line. The given graph is a straight line so its equation is of th...
Given a line in slope intercept form, y = mx + b, or a graph of a line, other lines can be found that are parallel or perpendicular to the given line. To find a line that is parallel, keep the slope the same, but change the y-intercept. To find a line that is perpendicular...
Step 2:Graph the {eq}y{/eq}-intercept. This point can be graphed as {eq}(0,b) {/eq}. Place this point on the graph. Step 3:Turn the whole number for the slope into a fraction, by writing the whole number in the numerator, and 1 in the denominator of ...
Vmass is equal to the inverse of density; hence, we can write: MW=RT(ρP)P=0 The best value for molecular weight is calculated from an extrapolation of ρ/P versus P to zero pressure. In other words, the intercept of line ρ/P versus P is MW/RT. Determine the ρ/P at each pr...
Three different exponential growth functions are graphed in the diagram below. The graph on the left helps show the role of 'b' in they=a⋅bxy=a⋅bx Namely, the greater the value of b the 'steeper' the curve looks the greater the rate of growth ...
(Graphed as In p against 1/T.) Tc is the critical temperature and Tt.p. is the triple point temperature. When vapor pressure data are collected over a large temperature range, or if the temperature variation of the enthalpy change is great, curvature of the ln p vs. 1/T plot may be...
