What is the slope-intercept form of the equation y - 7= -5/2(x+4)

Mathematics

GREYUIT [131]2 years ago

The first thing I would probably do is distribute (multiply) the -5/2 into the parenthesis:

= (-5/2)x + (-20/2)

Notice how I am not putting the x into the fraction. This is to make it easier to see the slope-intercept form.

Lets simplify the (-20/2) and then add 7 to both sides:

y - 7 = (-5/2)x - 10

y = (-5/2)x - 3

Your answer would then be:

y = (-5/2)x - 3

y = mx + b

Since it is now in the requested format.

Answer:

y=-\frac{3}{2}x+1

Step-by-step explanation:

Slope-intercept form means

y=mx+c

where m is given its the slope which is -\frac{3}{2} and we have the coordinates x and y which is (4, -5) and we need to find the value of c which is the y-intercept so we insert all these values into the equation so ,

y=mx+c

-5 = -\frac{3}{2}(4)+c

-5=-6+c

c=1

now we know the value of slope which is given -\frac{3}{2} and we found the value of which is 1 so we put these values into our original slope-intercept form equation

y=mx+c\\\\y=-\frac{3}{2}x+1
