The equation for a line is mx + b = y where m is the slope and b is the y intercept. To find the slope, we need to use the equation .
Therefore, m is equal to -1. Normally, we would then have to plug in m and one of the points to find b. However, because the point (0,5) is the y-intercept (the y-intercept is the point on the line where x is equal to 0), we can skip this step and go straight to forming the final equation, which is .
Answer:
Step-by-step explanation:
Subtract 3 from both sides:
Add x to both sides:
Divide 7 on both sides:
