Chapter 8.7, Problem 19PPS

To determine

To calculate: To graph $y=3x+4$ using the slope and y-intercept

Answer to Problem 19PPS

Graph for the equation is plotted.

Explanation of Solution

Given information: Equation is $y=3x+4$

Formula Used:

Slope intercept form of line is $y=mx+c$ , where

  $m=$ Slope of graph of equation

  $c=$ y-intercept of graph of equation

Calculation:

Equation is given as

  $y=3x+4$

Comparing the above equation to slope intercept form of line $y=mx+c$ , slope and Y-intercept are

  $\begin{array}{l}m=3\\ c=4\end{array}$

Thus, y-intercept is at $\left(0,4\right)$ , which is the first point

Also, $m=3$ , this means that one will rise 3(up) and run 1(to the right)

Thus, other point is $\left(1,7\right)$
