By graphing the given equations we can determine the number of solutions to the system. This will be the point at which the lines intersect. To do this we will need the equations to be in slope-intercept form to help us identify the slope m and y-intercept b.
Let's rewrite each of the equations in the system in slope-intercept form, highlighting the m and b values.
Given Equation | Slope-Intercept Form | Slope m | y-intercept b |
---|---|---|---|
y=2x−3 | y=2x+(-3) | 2 | (0,-3) |
y=x+4 | y=1x+4 | 1 | (0,4) |
