Question Graph a line with a slope -3 passing through the point (2,-4). The slope (gradient) is stated as a single value so this is a straight line graph Determined by the equation of the line y=mx+c
Question
Graph a line with a slope -3 passing through the point (2,-4)
Answer
The slope (gradient) is stated as a single value so this is a straight line graph
Determine the equation of the line
=-3
Let the given point be P1→(x1,y1)=(2,−4)
Using the equation of a straight line
Y= mx + C
Find the Value of C Using the points given that is P1→(x1,y1)=(2,−4)
Y= mx + C
-4 = -3 (2) + C
C= 2
The equation is then y=-3x+ 2
Plotting the Line in a line graph, find the equivalent y values for given set x values
| X Values | Y values |
| -4 | |
| -2 | |
The corresponding y values are as follows
| X Values | Y values |
| -4 | 14 |
| -2 | |
| -4 | |
| -10 | |
| -16 |
Thereafter we plot the graph as shown below
