graph this line using the slope and y - intercept: y = 7x + 2 click to select points on the graph.
Answer
Explanation:
Step1: Identify the y - intercept
The equation is in slope - intercept form $y = mx + b$, where $b$ is the y - intercept. For $y = 7x+2$, $b = 2$. So, plot the point $(0,2)$.
Step2: Identify the slope
The slope $m = 7=\frac{7}{1}$. From the y - intercept point $(0,2)$, move 1 unit to the right (increase $x$ by 1) and 7 units up (increase $y$ by 7) to get the point $(1,9)$. You can also move 1 unit to the left (decrease $x$ by 1) and 7 units down (decrease $y$ by 7) to get the point $(- 1,-5)$. Then draw a straight line through these points.
Answer:
Plot the points $(0,2)$, $(1,9)$, $(-1,-5)$ and draw a straight line through them.
