Answer:
Ben knows that a line passes through the point (-3, 8) and has a slope of -3/4, but he needs to find the equation of the line. Therefore, he should substitute 8 for_______
and he should substitute -3 for _________, and he should substitute -3/4 for __________ into the Point-Slope Formula. He will need to __________ and simplify before solving for y = mx + b form.
Explanation:
To use the Point-Slope formula to find the equation of the line, Ben should substitute the following values:
Substitute 8 for y, since the point (-3, 8) has a y-coordinate of 8.
Substitute -3 for x, since the point (-3, 8) has an x-coordinate of -3.
Substitute -3/4 for m, since the line has a slope of -3/4.
The Point-Slope formula is:
y - y1 = m(x - x1)
Substituting the values, we get:
y - 8 = (-3/4)(x - (-3))
Simplifying the right-hand side, we get:
y - 8 = (-3/4)(x + 3)
To get the equation in y = mx + b form, we can start by distributing the (-3/4) to the x and the 3:
y - 8 = (-3/4)x - 9/4
Adding 8 to both sides, we get:
y = (-3/4)x + 23/4
So the equation of the line is y = (-3/4)x + 23/4.
