Answer:
Step-by-step explanation:
From the given information, we already know two points the line intersects. It states that the line has a y-intercept of 3. The y-intercept is the point at which the line intersects the y-axis. Thus, the line also intersects (0,3). (Remember that all points on the y-axis have an x-value of 0.) Now we have enough information to write an equation.
1) Find the slope of the line with the slope formula, . Substitute the x and y values of (-5,2) and (0,3) into the formula and solve:
So, the slope of the line is .
2) Now we can write the equation in slope-intercept form, represented by the formula . Substitute values for
and
in the formula.
The represents the slope, so substitute
for it. The
represents the y-intercept, so substitute
for it. This gives the following answer and equation in slope-intercept form:
Answer:
Four less than an unknown value E)
Quotient of a variable and four B)
Some number to the power of four A)
Four times an unknown value D)
Four more than some number C)
Step-by-step explanation:
Let's analyze each statement separately:
- Four less than an unknown value --> this means that we have to subtract 4 to an unknown value. Calling the unknown value, it means we have to write
- Quotient of a variable and four --> this means we have to divide a variable by 4. Calling the unknown variabl, it means we have to write
- Some number to the power of four --> this means that we have to write the power of a number, in the form , where m in this case is equal to 4. Calling
the unknown number, it means we have to write
- Four times an unknown value --> this means that we have to multiply an unknown value by 4. Calling our unknown values, we have to write
- Four more than some number --> this means we have to add 4 to an unknown number. Calling the unknown number, it means we have to write
